Product Selection UL 9 Cable-In / Cable-Out Branch Circuit Breaker PRODUCT 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 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 characteristic acc. to UL 9 a conventional non-tripping current I nt = I N (T= ) b conventional tripping current I t = 1.
