QS2100H - 100Amp Circuit Breaker

QS2100H - 100Amp Circuit Breaker

When you replace a main circuit breaker, the right fit matters as much as the amperage. You need a breaker with the correct electrical ratings, connection style, and approval for the equipment it's going into. The Siemens QS2100H 100 Amp 2-Pole Circuit Breaker is a Type QSH plug-in breaker designed for compatible Siemens electrical distribution equipment. Rated at 100 amps and 120/240V AC with a 22kA interrupting capacity, it provides thermal-magnetic circuit protection for applications that require this breaker configuration.

Key Features and Benefits

• 100-Amp Current Rating: Provides the specified current capacity for electrical distribution applications designed around a 100-amp breaker.
• Two-Pole Protection: Designed for circuits and equipment requiring a two-pole breaker configuration.
• 120/240V AC Voltage Rating: Rated for systems with 120 volts between phase and ground and 240 volts between phases, as specified by Siemens.
• Thermal-Magnetic Trip Mechanism: Responds to both sustained overloads and short-circuit conditions.
• Type QSH Plug-In Connection: Designed for compatible electrical equipment that specifically accepts Siemens Type QSH breakers.
• Main Breaker Application: Part of Siemens' meter-load center combination mains product family.
