THQB32030 - 30A Circuit Breaker

THQB32030 - 30A Circuit Breaker

The THQB32030 is a 30-amp, 3-pole bolt-on circuit breaker built for protecting your three-phase electrical circuits from overloads and short circuits. As part of the Q-Line THQB series, it combines a secure bolt-on connection with a compact footprint, making it a practical choice for commercial and industrial panelboard applications.

Rated for 10,000 AIR at 240VAC, this molded case circuit breaker is designed to interrupt fault currents before they can damage connected equipment or wiring. The bolt-on mounting style helps you to create a solid electrical connection, which can be especially important in environments where vibration or frequent load cycling is present.

Because the THQB32030 is HACR rated, it is commonly used with heating, ventilation, air conditioning, and refrigeration equipment. It is equally at home in office buildings, retail facilities, warehouses, manufacturing spaces, and other locations where reliable circuit protection is required.
