General Electric | THLC134090 | Circuit Breaker | 3-Pole | 480V

Meet the General Electric THLC134090 Circuit Breaker—a robust, three-pole protection device designed for 480V three-phase systems. Built for maintenance, retrofit, and replacement scenarios, this GE part delivers reliable interruption when faults occur, helping protect motors, transformers, and distribution equipment in demanding industrial environments.

• Exact compatibility reference: This is a 3-Pole, 480V GE circuit breaker. Use the part number THLC134090 as the primary reference to confirm fit with your panel or equipment datasheet.
• Three-pole protection: All three phases trip together, minimizing the risk of phase imbalance and protecting connected equipment from partial faults that could cause damage or downtime.
• Direct retrofit utility: Designed to serve as a straightforward replacement or retrofit in systems that call out THLC134090, helping to reduce downtime and preserve system integrity during upgrades.
• Industrial-grade voltage rating: With a 480V rating, it is well-suited for motor feeders, MCCs, and other heavy-load circuits common in manufacturing, processing, and large commercial facilities.
• Fitment notes: Before ordering, verify that your equipment’s specifications align with this part. The part number remains the most reliable compatibility reference.

What problems does it solve? In three-phase networks, unmatched protection can leave one or two phases vulnerable during a fault, risking equipment damage and unplanned downtime. The THLC134090 ensures coordinated disconnection across all phases, helping maintain system safety and reliability in demanding environments.

Ideal use cases

• Protected motor circuits and drives in factories or warehouses operating at 480V
• Retrofits or upgrades for legacy GE panels and protection schemes that require this exact part
• New installations where a robust, GE-certified three-pole breaker is specified for 480V distribution

Practical installation and care tips

• Cross-check panel documentation to ensure mounting style and trip characteristics match your current protection scheme
• Always observe safety protocols: power down equipment, use lockout/tagout, and verify de-energization before handling components
• Keep the part number handy during ordering and service planning to guarantee continued compatibility across upgrades
