Siemens BQD325 - 25A, 3-Pole, Circuit Breaker

Meet the Siemens BQD325 — a 25A, 3-Pole circuit breaker designed for demanding 3-phase systems. Built to deliver dependable overcurrent protection in panelboards, switchboards, and control panels, it protects your critical loads while helping keep downtime to a minimum.

Why the BQD325 stands out

• Three-pole protection for all three phases — a single device that safeguards each phase in 3-phase circuits, ensuring coordinated interruption during faults.
• 25 A current rating— precise protection for common motor feeders and distribution circuits without nuisance trips, enabling safer and more reliable operation.
• Industrial-ready design — engineered for use in panelboards, switchboards, and control panels across industrial, commercial, and OEM environments where safety and reliability matter.
• Clear, straightforward integration — compatible with Siemens-based installations and retrofit projects, simplifying upgrades and maintenance in distribution panels and motor control centers.

Ideal applications

This circuit breaker shines in panelboards, switchboards, and control panels where robust three-phase protection is essential. It’s well-suited for industrial facilities, commercial electrical distributions, and OEM equipment builds that rely on reliable overcurrent protection for three-phase circuits and motor control centers.

How it protects your system

By detecting overcurrents and interrupting all three phases when needed, the BQD325 helps prevent damage to conductors, motors, and downstream devices. Its design supports safer maintenance by ensuring rapid isolation of faults, reducing arc energy and potential collateral damage in busy electrical environments.
