Siemens Q2110HH Molded Case Circuit Breaker HQP

Siemens Q2110HH is a 2-pole HQP molded‑case circuit breaker rated for 110 A at 120/240 V AC, designed for plug‑in mounting in Siemens QP/QPH/HQP panels with a common‑trip configuration. It provides thermal‑magnetic protection and carries a 65,000 A interrupting rating at 240 V, making it capable of interrupting high fault currents in typical distribution setups. As part of the HQP family, this two‑pole device matches Siemens’ high‑interrupting‑rating lineup for use with other QP/QPH/HQP breakers in standard 120/240 V systems, and is commonly used to protect feeders and branch circuits within Siemens load centers. The Q2110HH is specified for 120/240 V operation with an 110 A continuous rating, and its plug‑in form factor supports straightforward installation in compatible Siemens panels.
