BQ3D100 - 100Amp Circuit Breaker

BQ3D100 - 100 Amp Circuit Breaker

The BQ3D100 is a 3-pole, 100-amp bolt-on molded case circuit breaker designed for dependable circuit protection in commercial and industrial distribution panels. Built on the BQ frame platform, this breaker is rated for 10kA interrupting capacity at 240VAC and is HACR rated, making it suitable for heating, air conditioning, and refrigeration applications. With its bolt-on mounting configuration, the BQ3D100 provides a secure, stable connection to the panelboard bus, helping maintain proper contact and consistent operation. Designed for use in systems rated at 40°C, this breaker delivers the form, fit, and function required when replacing an existing BQ frame unit in compatible equipment.

Whether you’re maintaining an existing electrical distribution system or replacing a failed breaker, the BQ3D100 offers the correct amperage, pole configuration, and interrupting capacity needed to restore safe and reliable overcurrent protection.
