Siemens Q28000S01 U 80A 240V 2P Circuit Breaker

Siemens Q28000S01 is a Type QP, 2-pole molded-case circuit breaker rated at 80 A for 120/240 VAC, with a 10 kA interrupt rating—providing robust overcurrent protection for branch circuits in Siemens panel boards and compatible load centers. This model is the shunt-trip variant and ships with a 120 V shunt-trip coil included, enabling remote disconnection when safety interlocks or control logic demand it. With its two-pole design, it ensures simultaneous disconnection of both conductors on a fault, and its common-trip capability supports coordinated protection across phases in 120/240 V circuits. Market listings confirm its QP-type designation and the 80 A, 120/240 V specs; distributors such as Home Depot, Rexel, BayPower, Kirby Risk, and others catalog it as Q28000S01, underscoring its availability and established role in Siemens protection schemes. As part of the Siemens QP family, this breaker is designed for use in compatible panels and distribution equipment, offering reliable protection for feeders and branch circuits in residential and light commercial installations.
