General Electric TMQV22225MM 225A 2-Pole 240 V Circuit Breaker

The General Electric TMQV22225MM is a high-capacity, two-pole circuit breaker engineered for demanding 240-volt circuits. With a 225 A rating, this GE breaker provides robust protection for heavy-load feeders and equipment, helping to prevent electrical damage and downtime in commercial and industrial settings. Built to the trusted GE standard, the TMQV22225MM combines dependable performance with a straightforward installation experience for qualified technicians.

Key specifications

• Current rating: 225 A
• Poles: 2
• Voltage rating: 240 V
• Part number: TMQV22225MM
• Brand: General Electric (GE)
• Configuration: 2-pole, designed for 240 V circuits

Why this GE TMQV two-pole breaker stands out

Designed for high-current applications, the TMQV22225MM delivers reliable interruption of fault currents on both hot legs, safeguarding downstream equipment and wiring from overload conditions. Its two-pole design ensures synchronized protection for both conductors on a 240 V circuit, which is essential for motors, large HVAC units, and feeder circuits in building services. This specificity helps reduce the risk of arcing and uneven current flow that can occur with single-pole devices on multi-wire branches.

Ideal use cases

• Feeding large subpanels in commercial facilities where 225 A capacity is required
• Protection for high-current equipment such as large motors, compressors, and HVAC machinery
• Upgrading or configuring electrical panels in environments where 240 V, two-pole protection is appropriate

Installation and compatibility

Before installation, verify that your GE panel accepts TMQV-type breakers and that the wiring gauge and overall electrical design match a 225 A, 240 V two-pole configuration. As with all high-current protective devices, ensure power is fully isolated and follow all applicable electrical codes during replacement or installation. The TMQV22225MM is intended for use in GE panels that are specified for TMQV-series protection devices, providing a reliable, consistent fit with GE’s bus and mounting geometry.

Practical guidance for maximizing safety and performance

• Pair this breaker with appropriately rated conductors to prevent overheating and ensure safe protection margins.
• Keep panel labeling up to date to reflect the presence of a 225 A, 2-pole 240 V protection device.
• Schedule regular electrical inspections to confirm tight connections and verify there are no signs of wear or overheating in the panel interior.
