HJA36100AAYQ - 100 Amp Circuit Breaker
The HJA36100AAYQ is a 100-amp, 3-pole molded case circuit breaker that protects your commercial and industrial electrical systems from overloads and short circuits. Its thermal-magnetic trip unit reacts quickly to electrical faults while allowing normal currents to pass, keeping circuits and equipment safe.
With an I-Line plug-in design, this breaker installs easily in compatible panelboards and distribution equipment. It handles higher fault currents with interrupting ratings of 25kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC. A padlockable device provides an added safety measure for lockout/tagout during maintenance or service.
From manufacturing plants to commercial buildings, this breaker delivers straightforward protection for three-phase systems, making it a practical choice for everyday electrical operation.
