Siemens Q3100 3P 100A Plug-In Circuit Breaker

Siemens Q3100 is a three-pole, 100-amp plug-in circuit breaker in Siemens' QP/MP line for 240 V circuits. It uses a thermal-magnetic trip mechanism with a 10,000-ampere interrupting capacity (AIC) at 240 V, and is UL 489 listed for use in compatible load centers and panelboards. The compact 3-in. wide by 2-in. tall by 3-in. deep form factor fits Siemens plug-in installations that accept QP/MP breakers, and it features a plug-in connection for quick replacement. Electrical characteristics include 240 VAC operation, 3 poles, 100 A continuous current rating, and 10 kAIC interrupting capacity. Typical applications include distributing three-phase power in residential service panels or light commercial subpanels, feeding three-phase equipment, and serving as a feeder breaker in Siemens load centers that require the QP/MP family.
