Ideal use cases

This circuit breaker is suited for high-current, three-phase feeders in industrial facilities such as manufacturing lines, large motors, pumps, compressors, and HVAC systems. It’s particularly valuable in service entrances and main distribution panels where protecting multiple loads from a single fault is critical. If your setup relies on GE components or you’re replacing a worn unit in a GE panel that specifies the TK4VF36, this device provides a consistent, familiar form factor and trip characteristics you can trust.

Why choose the TK4VF36 over other options

Unlike generic breakers, the TK4VF36 is a GE-manufactured part designed to meet GE’s standards for performance and compatibility within GE systems. Its three-pole design ensures synchronized protection across all phases, reducing the risk of phase imbalances during faults. This specificity helps maintain stability in three-phase networks and simplifies service when paired with other GE components.

Practical considerations and installation notes

For optimal results, confirm that your equipment and panels are listed for the TK4VF36 part number and voltage rating. Install by a qualified electrician following local electrical codes, and refer to GE’s installation guidance for torque specifications and wiring diagrams. Regular inspection of connectors and mounting integrity will help maintain reliable performance in environments subject to vibration, temperature changes, and routine maintenance cycles.

Whether you’re upgrading an aging panel, configuring a new three-phase feed, or consolidating protection in a single, reliable GE solution, the General Electric TK4VF36 1200A 3-Pole 4 V Circuit Breaker delivers decisive overcurrent protection with the confidence that comes from a trusted GE component.
