GE SEHA36AT0150 - 150 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the GE SEHA36AT0150, a rugged 150A, 600V, 3-pole bolt-on molded case circuit breaker designed to protect branch circuits in panelboards and loadcenters. Its bolt-on mounting delivers a rigid, vibration-resistant connection to the bus, minimizing loose contacts that can cause nuisance trips or heat buildup.

Why it's built for reliable protection

• Thermal-magnetic trip unit: precisely responds to overloads and short circuits with stable, repeatable protection across temperature variations, reducing nuisance trips while quickly clearing faults.
• Bolt-on mounting: secure, field-proven installation that stays put in busy electrical panels, ideal for retrofit upgrades or new builds in demanding environments.
• OEM compatibility: designed to drop into matching GE OEM load centers and panelboards, ensuring correct fit, trip coordination, and labeling consistency.
• Three-pole design: ideal for 3-phase distribution in commercial and light industrial applications, while also serving multi-wire branch circuits in compliant panels.
