QS2110H - 110Amp Circuit Breaker

QS2110H - 110Amp Circuit Breaker

The Siemens QS2110H circuit breaker is a 110-amp, 2-pole, thermal-magnetic breaker designed to protect compatible electrical distribution equipment from overcurrent. Rated for 120/240V AC systems with a 22,000-amp (22kA) interrupting capacity, this Type QSH breaker combines overload and short-circuit protection in one device. It's a practical choice when you're maintaining an existing electrical installation that requires the QS2110H's specific electrical ratings and configuration.

Key Features and Benefits

• 110-Amp Current Rating: Provides overcurrent protection for circuits and equipment designed for a 110A breaker.
• 2-Pole Configuration: Designed for compatible two-pole applications in 120/240V AC electrical systems.
• Thermal-Magnetic Protection: Combines thermal overload protection with magnetic short-circuit protection.
• Type QSH Construction: Identifies the breaker family for accurate equipment and replacement verification.
• HACR Designation: Suitable for heating, air-conditioning, and refrigeration applications where the equipment specifications permit its use.
• Copper and Aluminum Conductor Compatibility: Accepts the specified #3 AWG–300 kcmil conductor range, subject to approved termination requirements.
