Siemens QJ22B110 - 110 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Siemens QJ22B110 is a robust, two-pole bolt-on molded case circuit breaker rated for 110A at 240V, purpose-built to safeguard branch circuits in panelboards and load centers. Designed for environments where reliability matters, its secure bolt-on mounting creates a rigid bus connection that stands up to vibration and reduces the risk of loose connections over time. Engineered for predictable protection, the thermal-magnetic trip unit delivers fast, repeatable response to overcurrent and short-circuit events. That means fewer nuisance trips and more consistent protection for your wiring and devices, even as load conditions shift throughout the workday. Why this breaker stands out - Secure bolt-on mounting: A sturdy connection minimizes movement and maintains alignment with the bus bars, enhancing long-term reliability in busy electrical panels. - Thermal-magnetic protection: Combines thermal slow-trip for overcurrent with magnetic instantaneous trip for high-energy faults, delivering dependable protection across a range of fault conditions. - Exact-fit compatibility: Built to pair with matching OEM loadcenters and panelboards, ensuring seamless integration in existing or rebuilt electrical systems. - Versatile application range: Suitable for residential, commercial, and light industrial installations where reliable 2-pole protection at 240V is required.
