Siemens B325M 25A 3-Pole 240 V Circuit Breaker

The Siemens B325M 25A 3-Pole 240 V Circuit Breaker is a precise, reliable protection device designed for modern electrical panels. With a 25-amp current rating and three poles, it safeguards three conductors on a 240-volt circuit, helping to prevent overloads and short circuits that can damage equipment or create safety risks.

Key features at a glance include:

• Current rating: 25 A
• Poles: 3
• Voltage rating: 240 V
• Part Number: B325M
• Manufacturer: Siemens

Why you’ll value the B325M

Designed for use in compatible Siemens panels, the B325M provides robust, repeatable protection for three-phase or multi-wire 240V circuits. Its three-pole design ensures all hot conductors in the protected circuit are simultaneously monitored, minimizing the risk of partial faults that can lead to equipment damage.

Ideal use cases

• Three-phase equipment in light commercial or industrial settings, such as pumps, motors, and conveyor systems
• Distribution circuits in panels that require a 3-pole 240V breaker for balanced protection across L1, L2, and L3
• Replacement breaker in Siemens-based installations that specify a B-series, 3-pole 240V solution

Practical considerations

Before installation, confirm that your electrical panel accepts Siemens B-series 3-pole 240V breakers and that the B325M matches the intended circuit’s current rating and voltage. Proper installation and adherence to local electrical codes are essential for safe operation. This breaker is positioned as a straightforward, compatible upgrade or replacement in suitable Siemens enclosures, delivering dependable performance for protecting downstream conductors and connected equipment.
