THQB2160ST1 - 60Amp Circuit Breaker

THQB2160ST1 - 60 Amp Circuit Breaker

The THQB2160ST1 is a 60-amp, 2-pole THQB series circuit breaker rated for use on your 120/240VAC systems. It features a factory-installed 120VAC shunt trip, allowing the breaker to be opened remotely when connected to a compatible control circuit. This makes it a good fit for applications where power needs to be disconnected automatically or from a remote location. The breaker uses a bolt-on mounting design and is part of the Q-Line product family, commonly found in commercial and industrial electrical distribution equipment. With a 10kA interrupting rating, it helps you to protect conductors and connected equipment from damage caused by overloads and short circuits. The breaker is also HACR rated, making it suitable for many heating, ventilation, air conditioning, and refrigeration applications. Compact in size and easy to integrate into compatible panelboards, the THQB2160ST1 is frequently used in building systems that incorporate emergency shutdown functions, fire alarm controls, safety interlocks, and equipment protection circuits.
