About fd3030.com
Thermomagnetic circuit breakers, like the FD3030 are the type found in most distribution boards. The FD3030 circuit breaker incorporates both instantaneous and long-time trip functions. The electromagnet characteristics of this breaker allow it to trip instantaneously under large surges in current (e.g., short circuits). A bimetallic strip within the breaker will respond to less extreme but longer-term over-current conditions.
