Tripping Curves to Choose From
Eaton WMZ branch circuit breakers are available with C and D tripping characteristics .
C-curve devices are suitable for applications where medium levels of inrush current are expected . Applications include small transformers, lighting, pilot devices, control circuits and coils . C-curve devices provide a medium magnetic trip point .
D-curve devices are suitable for applications where high levels of inrush current are expected . The high magnetic trip point prevents nuisance tripping in high inductive applications such as motors, transformers and power supplies .
Eaton WMZ devices are current limiting, which means they interrupt fault currents within one half cycle of the fault . Current limiting devices offer superior protection by reducing peak let-through current and energy .
Catalog Numbering System
Device Printing on Front and Side
Installation options
These branch circuit breakers are available in two terminal configurations: standard box terminals that accept multiple conductors and ring-tongue terminals, ideally suited to demanding requirements of the semi-conductor industry . All breakers mount on standard 35 mm DIN rail . Bus connectors and feeder terminal facilitate mounting and wiring of multiple miniature circuit breaker arrays in control panel assemblies . These circuit breakers can also be reverse feed .

Discover These Advanced Features Three Tripping Curves to Choose From
Eaton WMZS Supplementary Protectors are available with three different tripping characteristics, including Type B, C and D . Definitions for each trip curve are contained on the ordering pages and can be used to determine the optimal characteristic for your application . For example, low level short-circuit faults in control wiring, such as PLCs, are best protected by devices with Type B trip characteristics (3 to 5X continuous rating of the device (In) .
Even though not required by NEC or CEC for Supplementary Protectors, Eatons WMZS devices are current limiting, which means that they interrupt fault currents within one half cycle . Current limiting devices offer superior protection by reducing peak let-through current and energy .
