B220GFHH

The B220GFHH is a 2-pole Class A ground-fault circuit interrupter (GFCI) circuit breaker from Siemens, engineered for commercial and industrial branch-circuit applications requiring both overcurrent protection and personnel-level ground-fault protection. Rated for 20 at 240, this bolt-on breaker combines conventional circuit protection with sensitive ground-fault detection to help protect personnel from hazardous leakage-current conditions. Electrically, the B220GFHH provides Class A GFCI protection with a 5 mA ground-fault trip threshold and is designed to de-energize all ungrounded conductors when a qualifying ground-fault condition is detected. It carries an interrupting capacity of , providing high short-circuit interrupting performance for compatible Siemens distribution systems with elevated available fault current. Its combination of overcurrent protection and personnel-level ground-fault sensing makes the B220GFHH well suited for branch circuits where enhanced electrical safety is required. Mechanically, the B220GFHH uses a bolt-on mounting configuration for secure installation in compatible Siemens panelboard and distribution equipment. Its 2-pole construction supports 240 applications while providing simultaneous disconnection of the protected ungrounded conductors during qualifying overcurrent or ground-fault events. The molded housing and integrated electronic ground-fault sensing provide a compact protective solution for commercial and industrial electrical installations.
