QSH2150 - 150Amp Circuit Breaker

QSH2150 - 150Amp Circuit Breaker

If you need a 150-amp, 2-pole circuit breaker for a 120/240VAC system, the QSH2150 is built to handle the job. This thermal magnetic breaker is designed to protect electrical equipment from overloads and short circuits while providing a 42kA interrupting capacity for applications where higher fault current is available. The QSH2150 is commonly used in commercial and industrial electrical systems, including power distribution equipment and compatible HVAC applications. Its thermal magnetic trip mechanism responds to everyday overload conditions as well as sudden short circuits, helping protect connected equipment and reduce unnecessary downtime. The breaker also accepts #3 AWG through 300 kcmil copper or aluminum wire, making it a practical option for a variety of installation requirements. Whether you're replacing an existing breaker or installing compatible equipment, the QSH2150 offers the electrical ratings professionals look for without adding unnecessary complexity. Its compact design, HACR rating, and 40°C operating temperature rating make it a dependable choice for many demanding electrical environments.
