• Voltage rating: 600V

Why this GE breaker excels for your projects

When you’re upgrading or replacing components in a 600V three-phase distribution or motor-control network, the THEF136040 provides a precise fit and proven protective behavior. The three-pole configuration is ideal for circuits that require synchronized disconnection across all phases, helping prevent phase-to-phase faults and equipment damage. This isn’t a generic drop-in part—it's a deliberate match for GE panels and systems designed to accept 3-pole, 40-amp, 600V protection.

Who it's for and practical use cases

• Facilities managing three-phase motors, conveyors, pumps, or HVAC equipment operating at up to 600V.
• Maintenance teams performing retrofits in aging GE installations that need spec-matched replacements.
• Electrical engineers and technicians upgrading protection schemes in industrial control panels where a 40A, 3-pole, 600V breaker is specified.

What makes it stand out from the pack

• Exact part reference for compatibility: The part number THEF136040 is the best reference to ensure you’re ordering the correct match for your GE equipment and panelboard configurations.
• Clear, actionable specs: A defined 40A rating paired with 3-pole construction supports synchronized shutdown across all phases, improving system safety and fault isolation.
• Designed for demanding environments: Built to handle industrial loads typical of 600V distribution networks, giving you dependable protection where it matters most.

Installation and safety considerations

For safe, effective replacement or retrofitting, follow best practices and local electrical codes. Before ordering, confirm fit and ratings against your existing panel labeling and equipment manuals—the part number THEF136040 is your most reliable compatibility reference. When installing, shut off power and verify zero voltage, use appropriate PPE, and rely on a qualified electrician to complete the work. If you’re unsure about compatibility after reviewing the specs, taking a moment to double-check against your GE panel or equipment that accepts 3-pole 600V breakers will prevent mismatches.

Tips for optimal performance

• Keep the exact part number handy (THEF136040) when sourcing replacements to avoid mismatches in future maintenance.
• Use in circuits designed for 3-phase operation; avoid applying the breaker to single-phase configurations that require different protection specs.
• Document your replacement work in your facility’s maintenance logs to support traceability and future retrofits.
