FA36100 **Old Style** - 100 Amp Circuit Breaker

FA36100 **Old Style** - 100 Amp Circuit Breaker

The FA36100 Old Style is a 100-amp, 3-pole thermal-magnetic molded-case circuit breaker designed for use in compatible FA Series I-Line panelboards. When you're maintaining existing electrical distribution equipment, selecting a breaker with matching specifications is important for keeping the original system configuration in place.

The thermal magnetic trip mechanism helps protect your circuits by responding to both overload conditions and short circuits. Built to last, this molded-case circuit breaker is a practical solution for commercial and industrial facilities that need to maintain their existing FA Series electrical equipment without changing the original panelboard setup.
