QS2100HH - 100Amp Circuit Breaker

QS2100HH - 100Amp Circuit Breaker

When you replace a main circuit breaker, getting the right model matters. The Siemens QS2100HH is a 100-amp, 2-pole circuit breaker for electrical distribution applications, compatible with Siemens meter-load center combinations and load centers. As part of the Siemens Type QS family, this HQS breaker operates at 120/240V AC and offers a 65kA interrupting rating. Its plug-in connection and thermal-magnetic trip mechanism make it a practical choice for maintaining electrical equipment specifically designed to accept this breaker.

Key Features and Benefits

• 100-Amp Current Rating: Designed for electrical distribution equipment requiring a 100A circuit breaker.
• 2-Pole Configuration: Suitable for approved 120/240V AC main breaker and feeder applications.
• Thermal-Magnetic Protection: Combines overload and short-circuit protection in one breaker.
• Plug-In Electrical Connection: Designed for compatible Siemens equipment that accepts this connection style.
