Siemens BQD225 U Low Voltage Molded Case Circuit Breaker

Siemens BQD225 U is a two‑pole molded‑case circuit breaker (MCCB) rated for 25 A and up to 480 V AC, a member of the BQD family designed for low‑voltage protection in industrial and commercial power systems. This bolt‑on frame unit (frame size 100) is configured for easy installation in Siemens panelboards and switchgear, providing robust overcurrent protection for branch circuits and feeders. With an interrupting capacity of 14 kA at 480 V, it can safely interrupt fault currents encountered in typical distribution environments, helping to safeguard wiring and connected equipment. The BQD225 U designation identifies the model as a 2P, 25A device compatible with standard Siemens low‑voltage distribution architectures, making it a precise fit for installations that require a compact, reliable MCCB with a 480 V rating and solid fault‑current handling for routine industrial and commercial applications.
