Product Description

Thermomagnetic circuit breakers, like the LA36400 is commonly found in many Square D panels or distribution boards. The electromagnet characteristics of the [part allow it to trip instantaneously under large surges in current (e.g., short circuits). A bimetallic strip within the LA36400 will respond to less extreme but longer-term over-current conditions. The LA36400 is a common breaker for commercial or light industrial application; such as, lighting, small motors, printing presses or other electrically powered devices or outlets. This style of circuit breaker is sometimes used as a main breaker or a sub-feed to a sub panel.
