Siemens | BQ3B025L | Circuit Breaker | 25A | 3-Pole | 240V

Siemens BQ3B025L is a 25A, 3-Pole, 240V circuit breaker designed for reliability in protection of three-phase circuits. Built to serve as a maintenance, retrofit, or replacement solution, it ensures continued safety and shutdown control in Siemens panels that require this exact specification.

Key features include:

• Amperage: 25A
• Poles: 3-Pole
• Voltage: 240V
• Reference compatibility: The part number BQ3B025L is your best reference for matching panels and ratings

Why this breaker is a smart choice

• Designed specifically for Siemens panel ecosystems, making retrofits and replacements straightforward without adapters or guesswork.
• Compact three-pole configuration protects three hot conductors in 240V three-phase systems, simplifying wiring and reducing panel clutter.
• Direct match for projects that require a precise 25A trip limit and the BQ-series form factor, helping maintain consistent electrical protection across the installation.

Ideal use cases

• Maintenance and replacement in Siemens panels where a 25A, 3-Pole, 240V breaker is required.
• Retrofits or service upgrades for three-phase equipment such as motors, compressors, and HVAC gear in commercial settings.
• New installations in compatible Siemens panels that call for a 25A, 240V protection device.

Practical tips and safety notes

• Always confirm fit and ratings with the panel label and wiring diagram before ordering. The BQ3B025L is most reliably matched by its part number.
• Power down the main supply before removing or installing a breaker. Use appropriate PPE and follow local electrical codes.
• Ensure the circuit wire gauge and protection class meet the 25A rating and 240V application as specified for this model.
