Siemens Q220H U Two-Pole General Purpose Circuit Breaker

Siemens Q220H U is a 20-amp, two-pole molded-case circuit breaker in the QP/MP family, designed for 120/240 VAC service with plug-in mounting and Insta-Wire wiring capability. The unit accepts conductors from 14 AWG up to 6 AWG copper or aluminum and carries a 22 kA interrupt rating at 240 V, delivering reliable short-circuit protection for general-purpose branch circuits in Siemens load centers and panelboards. Its thermal-magnetic trip mechanism provides a standard trip response and the two-pole design ensures common-trip disconnection of both poles for enhanced safety. Configured as a QPH frame unit with load-lug terminal options on select configurations, the Q220H U is commonly used to protect lighting, receptacle, and small-appliance circuits in residential and light commercial distribution equipment, aligning with Siemens' QP/MP lineup for replacements in compatible panels. Designed for quick field replacement in existing Siemens panel systems, it supports standard QPH mounting and is compatible with related accessories and bus configurations used in residential load centers and panelboards.
