Product Features
According to the level of the rated ultimate short-circuit breaking capacity, the breaker can be classified into four types. Type C (Basic type), Type L (Standard type), Type M (Less high breaking type) and Type H (High breaking type). The breaker possesses the features such as compactness, high breaking capacity, short arc over and short resistance etc.
The breaker can be installed vertically (upright) as well as horizontally (crosswise).
The breaker have disconnecting function. Its corresponding symbol is shown as :
The breaker meets the criterion IEC 60947-2, GB 14048.2-2001 and has TÜV, CE and CCC certificates.

Alarm Contact and Its Combination
Wiring Schematic of Alarm Contact
When breaker is open or closed normally ,the contact is
not actuated. Only after tripping or breaking due to
defect, the position of the contact will be changed from
permanently open to closed or permanently closed to
open. The contact resets when breaker re-latches.

Undervoltage Release
Control voltage: AC 50Hz 230V110VDC
400V220V
Between 35%~70% of rated control voltage, undervoltage release should operate in security and trip breaker. When under 35% of rated voltage, it should prevent breaker from closing. Breaker closing is possible only if the power supply voltage is no less than 85% of rated voltage.
Note: Only undervoltage release be charged in advance, breaker can be closed or re-latches.

Shunt release is usually installed in A phase of breaker. Between 70%~110% of rated control voltage, shunt release should trip breaker in security under any operating conditions.
Note: Below shunt controlling loop design is recommended when the power of the controlling loop is DC 24V.
KA stands for the relay in DC 24V controlling loop. The current capacity of its contract is 1A.

Do not adjust the characteristic and accessories of the breaker, which handle by the
manufacturer.
The handle of the breaker can be placed in three positions, which represent CLOSED, OPEN
and FREE TRIP individually. When the handle is in the position of FREE TRIP, it should be
turned in direction of OPEN at this moment. Then the breaker can be re-latch and closed.
The user should conform to the regulations of the storage and application. Within 18
months after delivery from the manufacturer, if the product can not work properly or be
damaged because of the quality defect, the manufacturer is responsible for changing or
repairing without charge.
The model, specification and order quantity of the breaker should be noted. When using
undervoltage release, shunt release or motor operator, please give clear indication of
operation voltage or the value of control power voltage.
For example: NDM2-100L with undervoltage release and single auxiliary contact;
before-plate wiring type; Rated current 80A; Control voltage 220V; Quantity: 10 PCS. Then
you can order as following:
NDM2-100L/3371-H 80A 220V 10PCS
It should be declared, when the ambient temperature meets the following situation: Upper
limit over +40℃ or lower limited below -5℃.

Summary Product Features
New Generation Product
Application
Low-voltage distribution protection.
Motor protection.
Control broard protection.
Power transition system.
Various Models
3 poles

Complete range of accessories.
3-segment protection functions
The breaker can provide protection functions against overload, short-circuit with delayed trip and short-circuit with
instantaneous trip. It can be adjusted by customers according to the load current.
Self-power
Intellectual controller is powered by circuit breaker itself.
Pre-alarm indication
LED "Alarm" on the panel flashes and then lights solid when the actual current reaches or exceeds pre-alarm tripping
threshold Ip.
Overload indication
LED "Over" lights solid when the load current exceeds long-time overload tripping threshold.
Instantaneous tripping function at large current
Breaker is tripped directly by electromagnetic trip unit when there is large current (≥20Inm) during operation.
Interchange ability with NDM2 series MCCB
Same frame size have the same dimensions as NDM2 series MCCB. (The dimensions of frame size 630 and 800 are the same).
NDM2E Series Electronic Molded Case Circuit Breaker(hereinafter "breaker") is suitable for
in-frequency switching of circuits and starting of motors in 50Hz circuits with rated insulation voltage
of 800V, rated working voltage of 400V and rated current up to 1200A. The breaker can provide
overload, short circuit and undervoltage protection to the circuit and power equipment concerned.

Prevent breaker from closing when the voltage is under 35%
of rated voltage.
Breaker closing is possible only if the voltage is between 85% and 110% of rated voltage.
Note:Only undervoltage release be charged is advance, break can be closed or re-latches.
Connect the power according to the leading-out wire code. (It doesn't
matter if it's +/- of DC power).
Voltage: AC230V, 400V; DC 220V, 24V
Trips breaker reliably when control voltage is between 70% and
110% of its rated voltage.

MCCB in the switchgear may be operated with the handle in the front.
There are extended handle for both "F type" and "A type".
The switchgear shouldn't open when MCCB is CLOSED.
There is an emergency unlocking device on the handle for failures at CLOSED status.
Different handles have same cutouts dimensions.
Note: Customer should confirm with Liangxin in advance for the coordination between Nader breaker and other brand's motor operator/handle operating mechanism which are purchased by customers separately. Otherwise, Liangxin disclaim all responsibility for the damage caused by the coordination problem.

Application
NDM2L Series Molded Case Circuit Breaker (hereinafter “CBR”), of which insulation voltage is 690 V, will be suitable for in-frequency switching of circuits and starting of motors in 50Hz/60Hz circuits with rated working voltage of 400V and rated current up to 400A. The breaker can provide overload, short circuit and undervoltage protection to the circuit and power equipment concerned. In addition, it can also protect the circuit against fire disaster caused by long-term grounding error that can not be detected by over current protection device.
NDM2L series CBR is combined with NDM2 series MCCB and residual current protection modular. It has the characteristic of easy installation and flexible adjustment.
Working Condition
Altitude:≤2000m.Ambient temperature: -5℃~+40℃ (The average temperature in 24h should not exceed +35℃.) The relative humidity of the air does not exceed 50% at the maximum temperature of +40℃. Higher relative humidity may be prermitted at lower temperature. The average highest relative humidity should not exceed 90% when the lower average temperature of the most humid month is below +25℃. Special measures may be necessary in cases of occasional condensation due to variations in temperature.Pollution degree:3.The installing type of main circuit: Type Ⅲ. Auxiliary and controlling circuit which are not be connected to main circuit: Type II.Used in areas wirhout possibility of explosion, metal eroding and insulation destroying media and be free from rain and snow.

Undervoltage Release
Note: Below shunt controlling loop design is recommendedwhen the power of the controlling loop is DC 24V.
KA: The relay in DC 24V controlling loop. The current capacity of its contract is 1A.
Voltage: AC 50Hz 230V/400V; DC 220V. Between 70%~110% of rated control voltage, shunt release should trip breaker in security under any operating conditions.
Shunt Release
Wiring Schematic of Shunt Release (Internal accessory wiring schematic is shown in dashed frame.) K: Micro switch inside shunt release. It is connected with coil in series and normally closed. When breaker trips, the micro switch turn to open. When breaker is closed, the micro switch turn to closed.

Between 35%~70% of rated control voltage, undervoltage release should operate in security and trip breaker. When under 35% of rated voltage, it should prevent breaker from closing. Breaker closing is possible only if the power supply voltage is no less than 85% of rated voltage.
Note: Only undervoltage release be charged in advance, breaker can be closed or re-latches.

Usage and Maintennce
Do not adjust the characteristic and accessories of the breaker, which handle by the manufacturer. The handle of the breaker can be placed in three positions, which represents CLOSED, OPEN and FREE TRIP individually. When the handle is in the position of FREE TRIP, it should be turned in direction of OPEN at this moment. Then the breaker can be re-latch and closed.
Ordering Notice
The model, specification and order quantity of the breaker should be noted. When using undervoltage release, shunt release or motor operator, please give clear indication of operation voltage or the value of control power voltage. For example: NDM2L-100/4300B, Rear connection, Delay type, Rated current 80A, Quantity: 10 PCS.
