Description
A reliable solution for commercial power distribution, the Siemens HGB2B030B is a 2-pole, 30A molded case circuit breaker. It features a rugged GB frame construction with fixed thermal-magnetic trip technology for precise overcurrent and short-circuit response. This unit bolts securely into Siemens P1, P2, P3, P4, and P5 panelboards. For facility upgrades, it is replaced by the newer 3VA5130-6ED21-0AA0 model, which requires a specific mounting kit for installation.Specifications
