QSH2110 - 110 Amp Circuit Breaker

QSH2110 - 110 Amp Circuit Breaker

When your electrical system demands dependable circuit protection, the QSH2110 thermal magnetic circuit breaker delivers the performance professionals expect. Designed with a 110 Amp rating, a 2-pole configuration, and a 42kA interrupting capacity at 120/240VAC, this breaker helps protect electrical equipment from both overloads and short circuits before they can lead to costly damage or downtime. Its thermal magnetic trip mechanism combines two layers of protection in one compact device—responding to sustained overload conditions while reacting almost instantly to high fault currents. Whether you're replacing an existing breaker or outfitting a commercial or industrial electrical system, the QSH2110 is built to provide consistent, reliable protection in demanding environments. With HACR certification, a 40°C ambient rating, and compatibility with #3 AWG through 300 kcmil copper or aluminum conductors, it offers the flexibility needed for a wide range of electrical installations.
