Safety Breaker-Type Earth Leakage Circuit Breaker
This is a compact earth leakage circuit breaker that is approximately the same size as the optimal safety breaker for equipment protection.
The lineup consists of dedicated ground fault protection products (without OC) and products that include overload and short circuit protection (with OC).
Because the lineup contains a large variety of terminal variations (crimp terminals, tab terminals), these products can be used in a wide range of equipment including distribution panels, control panels, and inside equipment.
