HIGH-SPEED DC CIRCUIT BREAKERS, TYPE UR26, UR36 & UR40 - 3 KVDC2

APPLICATIONS

GENERAL INFORMATIONThe UR26, UR36 & UR40 are DC high-speed, current-limiting, circuit-breakers with natural cooling. They are trip free, single pole, bi-directional and equipped with electromagnetic blow-out, electric control circuits and direct over-current instantaneous release.With its simple design and high insulation level, the UR range offers a very high reliability as well as an exceptionally long lifetime.To guarantee a safe and optimized installation of its circuit-breakers in different environments, Sécheron offers a large range of standard and customized solutions. The circuit-breaker of the UR range can be delivered with an insulating housing, for indoor installation or, for outdoor use, in DC MODBOX® or in a polyester protective enclosure.

DC MODBOX® is a modular platform where the DC circuit-breaker is integrated alone or with other high and low voltage components (contactors, disconnectors, resistors, voltage and current sensors…) in a light and compact metal box. This way, rolling stock manufacturers can be supplied with a fully tested “Plug & Play” unit, easy to install and highly valuable for project management and logistics (refer to brochure SG580044BEN for more details).With its proven worldwide experience and acceptance, Sécheron’s circuit-breaker is the key product to guarantee the highest safety to rolling stock material and to the people operating or using it.

LOW VOLTAGE CONTROL SCHEME

/// ELECTRIC HOLDING E-TYPE

• The circuit breaker remains closed with a reduced ‘’holding’’ current. To open the circuit breaker the holding current is cut-off.

• With E-type closing device, the circuit breaker cannot remain closed if the low voltage supply is lost.

Sécheron’s scope

Customer’s scope

The UR breaker together with the ECO-Drive is fully compliant for electromagnetic compatibility with EN 50121-3-2 and with EN 50155: § 5.1.1.2 short (10 ms) interruptions class S2 and § 5.1.3: voltage dips / variation (at 0.6 Un during 100 ms) class C1.

ECO-Drive is a compact control module integrated with UR circuit breakers, to manage closing-holding sequences with electric control. ECO-Drive is set on the UR breaker ’s closing device.

UR26/36/40 breakers need no more additional hardware to manage the closing-holding sequences

Reduction of the overall space necessary to operate the circuit-breaker Reduction of overall installation costs of the DC circuit-breakers Reduction of holding power consumption and operational costs versus conventional

holding variant Reduction of the risks of damaging the closing coil during commissioning and service

operations.


Sécheron proposes 3 different concepts to integrate the UR26/36/40 circuit-breakers in vehicles:• Complete Plug & Play Roof-mounted polyester enclosure, in which

the DC circuit-breaker is installed, and which offers an IP54 protection index. It is intended for EMUs and trains outdoor roof mounting (including high speed trains).

• Insulation housing with protection index IP00, delivered as an option separately from the breaker. It enables the car-builder to build its own metal enclosure and/or container with reduced dimensions, in which the DC circuit-breaker with its insulation housing will be installed. This type is mostly used for locomotives and trains.

• Complete Plug & Play metal enclosure (DC MODBOX® program), in which the DC circuit-breaker is set with other functions, such as current & voltage measurements. DC MODBOX® offers an IP56 protection index for outdoor roof or underframe mounting. This type is mostly used for trains and high-speed trains, as well as for applications with severe operational environments (cold and icy, dusty or sandy environment).

/// DC MODBOX®

To evaluate DC MODBOX® solution that best suits your project, please contact Sécheron.

DC MODBOX® is a compact metal clad, “plug and play’’, project-based solution, featuring several high voltage DC components located around the DC circuit-breaker.Built on a standard platform of rolling-stock-dedicated aluminium enclosure and standard proven high voltage DC components, DC MODBOX® can be, to a certain extent, adapted to the application requirements. Typically electric schemes, integrated components, as well as both high- and low-voltage interfaces can be customized.

With its limited height (535 mm) and a shape designed to match aerodynamic constraints, DC MODBOX® bring efficient solutions to solve co nstraints related to roof space, insulation and speed. Moreover it allows the high voltage DC components to operate protected from the most severe environmental conditions. DC MODBOX® simplifies project management, logistics, and installation tasks for the car builder.
