CIRCUIT BREAKER
Well known for their proven reliability, Carling Technologies A-Series hydraulic magnetic circuit breakers are
compact, temperature stable and designed for precision operation in OEM markets requiring general purpose
as well as full load amp applications. When front panel operation and aesthetics demand a clean, contemporary
design, the visi-rocker or paddle actuators are ideally suitable. A sealed toggle actuator style is also available and
ideal for harsh environment applications requiring additional sealing protection. Optional rocker-guard and push-
to-reset bezels, which help prevent inadvertent actuation, are also available.
