ABB / General Electric TQ2150 Miniature Circuit Breaker

No. The TQ series is specifically UL-classified for use in Square D QO load centers. It is not designed for standard GE panels, which typically require THQL or THQP breakers.

The TQ2150 serves as a direct, UL-classified alternative to the Square D QO250 50-amp, 2-pole circuit breaker.

ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, this breaker may be branded as either ABB or General Electric, but the physical dimensions, fit, and function remain identical.

This 2-pole breaker requires two standard 3/4-inch spaces, totaling 1.5 inches in width, in a compatible Square D QO load center.

The box lug terminals accept 8 AWG to 3 AWG aluminum or copper conductors. Always ensure connections are torqued to the manufacturer specifications during installation.

Yes, this breaker is HACR rated, making it fully compliant for protecting heating, air conditioning, and refrigeration equipment that requires a 50A, 240V circuit.

Yes, it incorporates an internal common trip. If an overload or short circuit occurs on either leg, both poles will trip simultaneously to safely disconnect all power to the circuit.

The LI designation means the thermal-magnetic trip unit provides Long-Time (L) protection for sustained overloads and Instantaneous (I) protection for sudden short circuits.
