THHQB1170 - 70Amp Circuit Breaker

THHQB1170 - 70 Amp Circuit Breaker

The THHQB1170 is a 70-amp, 2-pole circuit breaker used in your compatible Q-Line panelboards and distribution equipment. It features a bolt-on mounting design that provides a secure connection to the panel and helps you to keep the breaker firmly in place during operation. Designed for branch circuit protection, this breaker helps protect electrical systems from damage caused by overloads and short circuits. The 22kA interrupting rating at 120VAC makes it suitable for installations where higher available fault current may be present. Because it is HACR rated, it can also be used in many heating, air conditioning, and refrigeration applications. With its compact molded case construction, the THHQB1170 is often found in commercial facilities, industrial buildings, and other applications where dependable circuit protection is required. Whether replacing an existing unit or servicing a panelboard, this breaker provides a straightforward solution for maintaining a safe and properly protected electrical system.
