Siemens HQJ3B125H01S11 is a molded case circuit breaker designed for primary overcurrent protection in industrial power distribution systems. This three-pole, 125A unit operates at 240VAC with a 100kA interrupting capacity and features thermal-magnetic protection with LI (Long-Time and Instantaneous) trip functions. The bolt-on connection design and compact construction ensure reliable installation in panelboards, while the integrated 25VDC shunt trip provides remote tripping capability for emergency shutdown scenarios. This HQJH Series breaker complies with UL and NEMA standards for commercial and industrial applications. Typical uses include motor control centers, lighting panels, and branch circuit protection in manufacturing facilities, data centers, and heavy machinery environments.
