General Electrics SGLL36BB0400 - 400 A, 3-Pole Bolt-On Circuit Breaker | AmpState

Introducing the General Electrics SGLL36BB0400 — a 400A, 3-pole bolt-on molded case circuit breaker engineered for dependable branch circuit protection in panelboards and load centers. Built to endure in demanding environments, its secure bolt-on mounting delivers a rigid, vibration-resistant bus connection so protection remains precise even under a busy electrical load.

• Secure bolt-on mounting ensures a durable, vibration-resistant connection to the bus bars, reducing movement, arcing, and intermittent trips in panels that see regular servicing or rugged use.
• Thermal-magnetic trip unit provides stable, repeatable protection by combining thermal overload sensing with an instantaneous magnetic trip for short circuits, minimizing nuisance trips across temperature swings.
• OEM-ready compatibility designed to fit GE OEM load centers and other panelboards that support bolt-on molded case breakers, making retrofit and upgrades straightforward without compromising safety.
• Three-pole protection supports three-phase circuits up to 400A, ideal for commercial and light-industrial applications where balanced protection and fast fault disconnection matter.
• Versatile applications suitable for residential, commercial, and light industrial panels, from service entrances to distribution panels needing robust main or feeder protection.

Technical snapshot

• Manufacturer: General Electrics
• Part number: SGLL36BB0400
• Type: Thermal-magnetic molded case circuit breaker
• Amperage rating: 400A
