HJA36100 - 100 Amp Circuit Breaker
The HJA36100 is a 100-amp, 3-pole molded case circuit breaker built for your commercial and industrial electrical systems. With its thermal-magnetic trip unit, it protects circuits and connected equipment from overloads and short circuits while allowing normal startup currents to pass. Its I-Line plug-in design makes installation and removal simple, and it’s equipped with dual-break rotating contacts that help reduce peak current during short circuit events.
This breaker handles high fault currents, with interrupting capacities of 25kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC, making it suitable for demanding power distribution applications. A built-in push-to-trip button provides you with easy manual testing, and a padlockable feature supports lockout/tagout safety procedures, giving maintenance teams extra confidence during service.
From manufacturing plants to commercial buildings, the HJA36100 delivers reliable protection and straightforward installation, making it a solid choice for three-phase electrical systems.
