Description
The FAL240301021 is a thermal-magnetic molded case circuit breaker built for commercial power distribution. Manufactured by Square D, this 2-pole, 30-amp unit provides reliable long-time and instantaneous (LI) protection. This unit-mount breaker installs into compatible Square D enclosures. For modern retrofits, it is replaced by the PowerPacT B-Frame (BGL26030) with an added shunt trip. The 1021 suffix indicates a factory-installed 120/240VAC shunt trip for remote operation.Specifications
