Hydraulic/Magnetic circuit breakers provide highly precise, reliable and cost effective solutions to most design challenges. They are considered temperature stable and are thus not appreciably affected by changes in ambient temperature.
Thermal circuit protectors utilize a bimetallic strip electrically in series with the circuit. The heat generated by the current during an overload deforms the bimetallic strip and trips the breaker.
Carling Equipment Leakage & Ground Fault Circuit Breakers combine the ground fault protection of a GFCI with the familiar overcurrent tripping characteristics of a normal circuit breaker.
