THQL2150 - 50Amp Circuit Breaker

THQL2150 - 50 Amp Circuit Breaker

The THQL2150 is a 50 amp, 2-pole circuit breaker designed to protect 120/240V electrical circuits from overloads and short circuits. Built for use in compatible Q-Line load centers and panelboards, this plug-on breaker provides a simple way to help you keep electrical systems operating safely.

A 50 amp breaker is often used for larger electrical loads that require dependable protection. The THQL2150 is commonly found in applications such as air conditioning equipment, electric water heaters, subpanels, and other circuits that draw more power than standard branch circuits. Its HACR rating also makes it suitable for heating, air conditioning, and refrigeration equipment.

The compact molded case design installs directly into compatible panels using a plug-on connection, helping you to reduce installation time. With a 10kA interrupting rating at 120/240VAC, the breaker is built to respond when fault conditions occur, helping protect connected equipment and wiring from damage.

Whether you're replacing an existing breaker or maintaining an electrical distribution system, the THQL2150 offers the dependable performance expected from the Q-Line series.
