Three Tripping Curves to Choose
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 wir-
ing, such as PLCs, are best protected by devices with Type B trip
characteristics (3 to 5X continuous rating of the device (I
Even though not required by NEC or CEC for Supplementary
Protectors, Eaton’s WMZS devices are current limiting, which
means they interrupt fault currents within one half cycle. Current
limiting devices offer superior protection by reducing peak let-
through current and energy.
