General Electric | THEF136090 | Circuit Breaker | 90A | 3-Pole | 600V

General Electric THEF136090 Circuit Breaker offers dependable three-pole protection for 3-phase systems up to 600V. Whether you’re maintaining, retrofitting, or replacing a panel, this 90A device matches the essential specs for a secure, code-compliant shutdown and restart.

• Amperage: 90 A
• Poles: 3-Pole
• Voltage rating: 600 V
• Part number reference: THEF136090

Why it matters

In a three-phase distribution network, a 3-pole breaker like THEF136090 protects all three hot conductors simultaneously. A 90-amp rating makes it suitable for mid-range feeders, motors, or equipment banks where overload protection is critical. Using the exact part number helps ensure compatibility with GE panels and with any installation that specifies this exact device, reducing the risk of fitment issues during critical maintenance windows.

Ideal use scenarios

• Maintenance on existing GE equipment or any panel that requires a 3-pole, 90A breaker
• Retrofit projects where a 90A, 3-pole device is needed to upgrade system protection
• Replacement of a failed breaker in commercial or light-industrial electrical rooms
• Three-phase motor circuits, feeders, or distribution points that require reliable overload protection at 600V

How to verify and install

• Check that your panel’s catalog or label calls for a 3-pole, 90A breaker with a 600V rating and that THEF136090 is the correct part reference for compatibility.
• Confirm any manufacturer-specific requirements (tolerance, trip curve, and mounting style) before ordering.
• Follow safe, lockout-tagout procedures and the panel’s installation guide when swapping breakers.

GE reliability, built for durability

With GE engineering, this circuit breaker is designed to withstand frequent operation in demanding environments. The part-numbered approach—THEF136090—helps ensure you’re selecting the exact device your system expects, simplifying ordering and reducing downtime caused by mismatched replacements.
