GE TEF134C5040 - 40A, 3-Pole, Circuit Breaker

Meet GE TEF134C5040 — a dependable 40A, 3-Pole circuit breaker engineered for robust overcurrent protection in demanding electrical systems.

Designed for use in panelboards, switchboards, and control panels, this GE circuit breaker delivers reliable performance for 3-phase applications, helping protect motors, drives, and distribution circuits from overloads and short circuits.

• Current rating: 40A
• Poles: 3-Pole
• Breaker type: Circuit Breaker

Why choose this model? In a three-phase setup, a 3-pole breaker ensures all conductors trip together, preventing phase-to-phase damage and providing a safer shutdown for critical equipment in MCCs and industrial panels. Built to endure the rigors of commercial, industrial, and OEM environments, it supports consistent protection across motor control centers and distribution panels.

Ideal use cases include:

• Industrial panelboards and control rooms requiring reliable 3-phase protection
• Motor control centers (MCCs) where synchronized disconnection reduces startup surges and fault propagation
• Commercial electrical rooms that need compact, dependable overcurrent protection

With the GE TEF134C5040, you’re choosing a component designed for longevity and clear electrical safety, backed by GE’s engineering heritage. It’s not just a breaker—it’s a guardrail for your electrical system, enabling predictable trips, safer maintenance, and easier fault diagnosis when issues arise.

Installation and maintenance tip: ensure proper tightening and verify compatibility with your panelboard or switchgear to optimize performance. For OEM integrations, this model’s 3-pole configuration provides flexibility in space-constrained layouts while delivering synchronized protection across three phases.
