Key specifications

• Brand: General Electric
• Part Number: SGLB36BA0150
• Current rating: 150 A
• Poles: 3
• Voltage rating: 600 V

Why a 3-pole design matters

A 3-pole circuit breaker protects all three hot conductors in a three-phase system, ensuring balanced protection across the phase legs. This minimizes the risk of partial energization that can damage motors, feeders, and control circuits, and it provides a straightforward main protection point for larger electrical loads.

Ideal use cases

• Protection for 3-phase motors, conveyors, and heavy machinery
• Feeding large HVAC systems and commercial lighting circuits
• Main service protection or subpanel protection in mid-size commercial environments
• Electrical distribution feeders where reliable trip performance up to 150 A is required

Installation & compatibility

Designed to work in GE-compatible panels and with standard bus stabs, the SGLB36BA0150 should be installed following the panel’s wiring diagram and torque specifications for termination screws. Maintain adherence to the device’s 600 V rating and ensure clean, secure connections to maximize longevity and reliable operation.

Performance and practical benefits

Choosing a dedicated 150 A, 3-pole breaker provides precise protection for three-phase circuits, helping prevent overheating and equipment damage during overloads or short circuits. It streamlines maintenance by offering a clear, single-point protection strategy for complex electrical layouts, reducing downtime and increasing system reliability.

If you’re outfitting a GE panel or upgrading a three-phase protection strategy, the General Electric SGLB36BA0150 150A 3-Pole 600 V Circuit Breaker delivers dependable, field-proven performance designed to meet the demands of modern electrical installations.
