Description
Operating as a 3-pole, 110A molded case circuit breaker, the Siemens HGB3B110B delivers a 35kAIC interrupt rating at 480Y/277V. It features fixed thermal and magnetic trip elements for demanding commercial environments. The breaker mounts into Siemens P1 through P5 panelboards via a standard bolt-on connection. For modern upgrades, this legacy SENTRON GB frame model is replaced by the 3VA5111-5EC31-0AA0, though the newer frame will require an adapter kit for panel installation.Specifications
