General Electric | THKM31200 | Circuit Breaker | 1200A | 3-Pole | 600V

Meet the General Electric THKM31200 circuit breaker — a purpose-built protection device designed to safeguard high-capacity, three-phase power distribution. With a 3-pole configuration, 1200A current rating, and a 600V operating range, this GE breaker is engineered to keep demanding systems up and running while guarding against overloads and faults.

Key specifications that matter

• Amperage: 1200A — handles substantial fault currents while protecting upstream equipment and downstream feeders.
• Poles: 3-Pole — ensures synchronized protection across all three phases for balanced, reliable 3-phase operation.
• Voltage rating: 600V — suitable for a wide range of commercial and industrial distribution setups.

Why this matters for maintenance, retrofit, and replacement The THKM31200 is identified by its exact part number, making it the most reliable reference when matching existing GE panels, feeders, or bus assemblies. Before ordering, confirm fit and ratings against your panel documentation to ensure a safe, compliant installation.

Use cases and practical applications

• Maintenance replacements in GE-installed panels where the THKM31200 footprint and specifications match existing equipment.
• Retrofits for 3-phase systems that require higher current protection without changing the panel layout.
• Reliable replacement in GE-based electrical infrastructures, preserving original performance characteristics and protection schemes.

What makes it stand out

This GE circuit breaker isn’t a generic substitute. Its 3-pole design aligns with three-phase distribution needs, delivering cohesive protection across all phases and maintaining consistency with GE’s engineering standards. The 1200A rating is tailored for environments with heavy electrical demand, helping minimize downtime and maximize system resilience.

Practical notes for selection and installation

• Always verify the exact part number against your panel’s documentation—the THKM31200 reference is your best indicator of compatibility.
• Ensure the system’s fault-current levels, conductor sizes, and panel specifications align with a 1200A, 600V, 3-Pole device to guarantee proper protection and safe operation.
• If there’s any uncertainty about fit, refer to the panel’s datasheet or consult a qualified electrical technician before purchasing.

Elevate your power protection with a trusted GE solution designed for durable performance in demanding 3-phase environments. Add the THKM31200 circuit breaker to your cart and secure a precise, dependable 3-pole, 600V protection option for high-capacity applications.
