General Electric | SEPA36AI0150 | Circuit Breaker | 150A | 3-Pole | 600V | Bolt-On

General Electric SEPA36AI0150 is a rugged 3-pole circuit breaker engineered for demanding 600V three-phase electrical systems. With a 150A rating and bolt-on mounting, this device is built for reliable protection in industrial panels, service equipment, and retrofit projects where exact specifications matter.

What this breaker does for you

As a protective device, it interrupts fault currents to safeguard wiring and equipment, helping prevent damage from overloads and short circuits. The 3-pole design provides coordinated protection across all three phases, making it ideal for three-phase distribution and motor circuits in commercial and light industrial environments.

Key specifications

• Amperage: 150A
• Poles: 3-Pole
• Voltage rating: 600V
• Mounting: Bolt-On

Why choose the SEPA36AI0150 for your panel

This GE part is purpose-built for maintenance, retrofit, and replacement scenarios where exact compatibility is non-negotiable. The bolt-on design provides a solid, secure connection to the panel bus, reducing the risk of loose terminations that can cause nuisance trips or arcing. By selecting the SEPA36AI0150, you’re choosing a component that aligns with existing GE bolt-on architectures, helping to minimize installation guesswork and downtime.

Installation and compatibility tips

Before ordering, verify fit and ratings to ensure a seamless swap:

• Use SEPA36AI0150 as the best compatibility reference when matching breakers to your panel model and bus configuration.
• Confirm that your panel supports bolt-on GE breakers and that the three-pole, 150A configuration aligns with your circuit design.
• Plan for proper de-energization and safe handling during replacement, following all on-site safety procedures.

Use cases and ideal applications

Ideal for facilities upgrading or expanding three-phase distribution, this breaker accommodates motor control circuits, HVAC equipment, and industrial machinery that require dependable overcurrent protection at 150A. It’s well-suited for retrofit projects where a legacy panel needs a precise, OEM-matched replacement without altering buswork or protective coordination.

Practical considerations

While this part delivers a straightforward, drop-in replacement for compatible GE bolt-on panels, always confirm the panel’s compatibility with bolt-on, three-pole 150A devices. Keeping a spare SEPA36AI0150 on hand can reduce downtime during planned maintenance or unexpected outages, ensuring you stay ahead of electrical interruptions.

In short, the General Electric SEPA36AI0150 delivers reliable, three-phase protection with a precise fit for GE bolt-on panels. Its 150A capacity, 3-pole configuration, and 600V rating make it a targeted solution for critical industrial and commercial circuits where exact specifications and secure mounting matter most.
