Why this GE circuit breaker stands out

The three‑pole design is ideal for protecting three‑phase circuits, helping to keep all phases safeguarded in industrial or commercial electrical systems. A 600V rating broadens its applicability to higher‑voltage panels, while the 45A current rating provides targeted protection for circuits with moderate load. Because it’s identified by a precise GE part number (THEF136045), it simplifies ordering and cross‑referencing, reducing the risk of mismatches during retrofit or replacement work.

Ideal use cases

Use this breaker for:

• Replacing a failed GE breaker in compatible panels
• Retrofit projects where a 3‑phase, 45A, 600V solution is required
• Maintenance tasks that demand an exact part number reference for compatibility

Compatibility and verification tips

To ensure a perfect fit, verify:

• Your panel or equipment list supports a 3‑pole, 45A, 600V circuit breaker
