BQD325 - 25Amp Circuit Breaker

BQD325 - 25Amp Circuit Breaker

The Siemens BQD325 is a 25-amp, 3-pole circuit breaker designed for use in 480/277VAC electrical distribution systems. It helps protect your circuits from overloads and short circuits and is commonly installed in panelboards serving lighting systems, HVAC equipment, pumps, and other three-phase loads. The thermal magnetic trip unit provides protection against both prolonged overcurrent conditions and sudden fault currents, making it a practical choice for your everyday commercial and industrial applications.

Built with a molded case housing and designed for panelboard mounting, the BQD325 is often used in offices, schools, healthcare facilities, warehouses, and manufacturing environments.
