QS2150HH - 150A Circuit Breaker Description
QS2150HH - 150A Circuit Breaker
If you need a 150 amp, 2-pole circuit breaker that can handle higher fault-current applications, the QS2150HH is built for the job. This Type HQS thermal magnetic circuit breaker is rated for 120/240VAC systems and offers a 65kA interrupting capacity, making it a dependable choice for protecting feeders, distribution equipment, and large electrical loads.
The thermal magnetic trip unit provides two levels of protection. It responds to long-term overloads while also reacting almost instantly to short-circuit conditions, helping reduce the risk of damage to connected equipment. The breaker is also HACR rated, making it suitable for heating, air conditioning, and refrigeration applications where dependable circuit protection is important.
Installation is straightforward thanks to a terminal range that accepts #3 AWG through 300 kcmil copper or aluminum wire. Whether you're replacing an existing breaker or maintaining a commercial or industrial electrical system, the QS2150HH offers the electrical ratings and performance professionals expect without adding unnecessary complexity.
