Siemens BG315 15A 3-Pole 240 V Circuit Breaker

The Siemens BG315 15A 3-Pole 240 V Circuit Breaker is a robust safety device designed to protect your 240-volt, three-pole electrical circuits. Built to slot into Siemens panels and compatible enclosures, this breaker delivers reliable overcurrent protection for demanding loads in both residential and commercial settings.

• Current rating: 15 A
• Poles: 3
• Voltage rating: 240 V
• Part number: BG315
• Compatibility: Designed for Siemens panels and compatible enclosures that support 3-pole 240 V breakers

Ideal for safeguarding three-phase equipment, multi-wire branch circuits, and demanding loads such as commercial lighting, HVAC equipment, or motor-driven systems, the BG315 helps prevent wiring damage and protects devices from overloads. By interrupting current flow when a fault or overload occurs, it reduces the risk of electrical fires and equipment failure, helping you maintain safer, more reliable operation of your electrical system.

Why choose the BG315 in your Siemens ecosystem?

• Consistent protection within the Siemens lineup: Designed to work as part of a coordinated protection strategy in compatible panels, ensuring predictable trip behavior and easier maintenance.
• Simple replacement and maintenance: Uses standard mounting and connection configurations to streamline swapping for service or upgrades.
• Versatile application: Suitable for 240 V three-pole circuits common in commercial spaces and advanced residential setups that require three-phase protection.

Practical tips for use:

• Verify your panel’s compatibility with three-pole 240 V breakers before installation to ensure proper fit and safe operation.
• Keep a BG315 on hand as a spare to reduce downtime when replacement is needed in a Siemens panel.
• When replacing an older breaker, confirm the new BG315’s trip rating matches the circuit’s load requirements to maintain protective coordination.
