CHB220 - 20Amp Circuit Breaker

CHB220 - 20 Amp Circuit Breaker

If you’re maintaining a panel that uses the CHB frame style, the CHB220 circuit breaker is designed to match those original specifications. This is a 2-pole, 20-amp bolt-on breaker rated at 120/240VAC with a 10kA interrupting capacity. It installs directly onto the panel bus with a bolted connection, helping ensure a firm and stable fit inside compatible CHB panelboards.

The CHB220 is typically used to protect branch circuits serving lighting, outlets, and similar loads in commercial or light industrial settings. When an existing breaker needs to be replaced, matching the amperage, voltage rating, interrupting capacity, and mounting style is critical. This model is built to last and intended to provide the same form, fit, and function as the original device in CHB systems.

Key Features and Benefits
