HGB3B020B - 20 Amp Circuit Breaker

HGB3B020B - 20 Amp Circuit Breaker

The HGB3B020B is a 3-pole, 20 amp molded case circuit breaker designed for panelboard applications. It has an interrupting rating of 35kA at 480VAC and 100kA at 240VAC, making it suitable for electrical systems where higher fault current protection is required. This breaker is rated for operation at 40°C, is HACR rated, and comes with load-side terminals already included. Whether you're replacing a failed breaker or stocking spare electrical components, the HGB3B020B provides the ratings and configuration needed for many commercial and industrial panel installations.
