8 Miniature Circuit Breakers and Supplementary Protectors UL 077 DIN Rail Supplementary Protectors. Technical Data and Specifications Trip Curve Charts 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 wiring, such as PLCs, are best protected by devices with Type B trip characteristics ( to X continuous rating of the device (I n ). 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.
