General Electric SEHA36AT0150 Plug Circuit Breaker

General Electric SEHA36AT0150 is a three-pole plug-in circuit breaker with a 150 A current rating and a 600 V maximum rating, built for use in GE panelboards that accept plug-in protective devices. The 3P configuration provides protection on all three phases of a typical 3‑phase electrical system, deterring overcurrent events on feeders and branch circuits while enabling clear fault isolation in commercial and light industrial power distribution. The plug-in mounting design supports fast installation and straightforward field replacement in compatible GE distribution panels, helping technicians swap units without disassembling large sections of the bus or enclosure. Although compact, the SEHA36AT0150 is engineered for reliable operation in demanding environments, with a form factor that integrates with GE protection schemes to coordinate with upstream and downstream protection devices. This part designation—SEHA36AT0150—highlights its role in GE’s plug-in breaker lineup and its suitability for high-current, multi-phase applications where easy serviceability and consistent protection are priorities.
