WMZS - UL 1077 - Supplementary Protectors
Eaton WMZS 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.
Available with "B", "C", and "D" tripping characteristics.
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)
