QSH2200 - 200Amp Circuit Breaker

QSH2200 - 200Amp Circuit Breaker

The QSH2200 is a 2-pole, 200 Amp thermal magnetic circuit breaker designed for use in 120/240VAC electrical distribution systems. It provides protection against overloads and short circuits and features a 42kA interrupting rating, making it suitable for applications where higher fault-current capacity is needed. This breaker is HACR rated for 60Hz applications and calibrated at 40°C. It accepts #3 AWG through 300 kcmil copper or aluminum conductors, giving installers flexibility when matching existing wiring. The thermal magnetic trip unit combines inverse-time overload protection with an instantaneous response to short-circuit conditions, helping protect connected equipment during abnormal electrical events. Whether you're replacing an existing breaker or servicing compatible electrical equipment, the QSH2200 offers the ratings and performance expected for many commercial and industrial power distribution applications.
