Siemens BQD325 3 Pole Industrial Grade Circuit Breaker

The Siemens BQD325 serves as a three-pole industrial grade circuit breaker engineered to provide essential overcurrent protection within commercial and industrial electrical distribution systems. Rated for 25 amperes, this unit supports stable operation across voltage levels spanning 277 volts up to 480 volts, enabling secure power delivery for multi-phase loads commonly encountered in heavy infrastructure applications. Because it utilizes a 3 pole architecture, the device ensures complete electrical isolation across all phase lines simultaneously during maintenance events, eliminating risks associated with residual energy in partially disconnected circuits. This breaker integrates directly into compatible panelboards, offering manual control capability to isolate circuits for safety inspections or emergency shutdown scenarios where rapid physical interruption is required. By combining 3 pole capacity with defined amperage thresholds, the BQD325 protects associated wiring and equipment from thermal overload conditions that occur during sustained excess current flow.
