Why this 3-Pole, 50A breaker matters

Designed for three-phase protection, the 3-pole configuration ensures all three hot conductors are interrupted simultaneously during a fault. This is essential for balanced motor loads, HVAC compressors, pumps, and other three-phase equipment, helping to prevent phase imbalance, equipment damage, and safety hazards. With a 50 A rating, it’s suitable for circuits where motors or equipment draw current up to 50 amps under normal operation, providing reliable protection against overcurrent conditions.

Ideal use cases

• Replacement in GE panels that require THEF136M1050
• Protection for three-phase motors and equipment in industrial or commercial settings
• Panelboard or distribution board upgrades where source equipment specifies the THEF family
• Maintenance and service work where exact GE compatibility is critical

What makes this GE part unique

Unlike generic substitutes, this circuit breaker is built to match GE’s electrical characteristics and mounting geometry, ensuring plug-and-play compatibility in compatible GE panels. The THEF136M1050 designation helps technicians quickly verify part identity, reducing installation errors and mis-matches. Its GE lineage supports consistent supply, predictable replacement cycles, and long-term serviceability in your electrical system.

Installation and practical notes

To get reliable protection, verify the breaker’s compatibility with your GE panel model and the THEF family specifications. Follow standard electrical safety practices: de-energize the system, secure proper wiring, and tighten terminations to the recommended torque per GE guidelines. Use in circuits where three-phase protection and 600 V maximum voltage alignment with your distribution system is required.
