QS2110 - 110Amp Circuit Breaker

QS2110 - 110Amp Circuit Breaker

When it's time to replace a main circuit breaker, the right fit is about more than matching the amperage. The Siemens QS2110 is a 110-amp, 2-pole circuit breaker designed for electrical distribution applications in compatible Siemens load centers and meter-load center combinations. As part of the Siemens Type QS family, it operates at 120/240V AC and provides a 10kA interrupting rating. Whether you're maintaining an existing electrical system or replacing a breaker at the end of its service life, the QS2110 offers the ratings and configuration needed for equipment approved to accept this model.

Key Features and Benefits

• 110-Amp Current Rating: Designed for electrical distribution applications requiring a 110A main or feeder circuit breaker.
• 2-Pole Configuration: Provides overcurrent protection for applicable two-pole circuits in compatible 120/240V AC systems.
• Thermal-Magnetic Protection: Responds to sustained overloads and short-circuit conditions through separate thermal and magnetic trip functions.
• Siemens Type QS Design: Helps identify the correct breaker family when servicing approved Siemens electrical equipment.
• Main Breaker Application: Part of Siemens' Meter Load Center Combo Mains family for compatible distribution equipment.
