UL 489 Cable-In / Cable-Out Branch Circuit BreakerWMZ Circuit BreakersPRODUCT SELECTION


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 .

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 .

Tripping Signal Switch WMZSAUXTRIP, WMZTAUX

• Design according to IEC/EN 60947-5-1, IEC/EN 62019

• Field installable

• The specified minimum voltages are per contact—take into account particularly in case of series connection

• Self-cleaning contacts

• Contact material and design particularly suitable for extra low voltage

• WMZSAUXTRIP: the function of one of the two change-over contacts can be switched from “auxiliary switch” to “tripping signal switch”

• Tripping signal contact transmits message of electric tripping, not mechanical switch-off

• Test key for contact function “electrical tripping”

• WMZTAUX: will allow for > 480Y/277 Vac rating

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, Eaton’s 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 .
