FGL37DA630NF Circuit Breaker

Feature & Principle

It is molded case circuit breaker for low-voltage power distribution loop. The thermal element responds to overload current and triggers delayed trip; the magnetic element responds to large short-circuit current for instantaneous trip. It can protect cables, transformers and downstream loads against overload, short circuit. Compact molded housing, easy installation inside power distribution cabinet.
