Siemens 5SJ4218-7HG41 Circuit Breaker, 15A, 2-Pole, 240V

Meet the Siemens 5SJ4218-7HG41 Circuit Breaker—a purpose-built 15 A, 2-pole device crafted for rugged industrial electrical service, maintenance, and replacement projects. Designed for 240V systems, this breaker provides reliable protection to keep your equipment and operations operating smoothly by interrupting fault currents when they occur.

Key specifications

• Part Number: 5SJ4218-7HG41
• Product Type: Circuit Breaker
• Amperage: 15 A
• Poles: 2
• Voltage: 240V

Why the two-pole design matters

The 2-pole configuration ensures both hot legs in a 240V circuit are disconnected simultaneously. That means safer disconnects, more consistent protection for dual-line circuits, and reduced risk of backfeed or partial energization during faults. Built for industrial environments, this Siemens breaker is engineered to perform in demanding service conditions where reliable protection is essential.

Compatibility and fit guidance

To ensure a precise match for your panel or distribution setup, verify fit by the part number and your application requirements. If you’re unsure about compatibility, reach out with the part number 5SJ4218-7HG41 and your system details—our team can help confirm whether this breaker suits your load, panel, and wiring configuration.

Ideal use cases

• Replacement of a failed or aging 240V, 2-pole circuit breaker in industrial panels
• Protection for critical 240V distribution circuits in manufacturing, warehousing, or facilities maintenance
• Upgrading legacy protection in service entrances or dedicated equipment circuits

Practical considerations for installation and operation

Plan for standard safety practices and follow manufacturer guidelines when installing. The 240V rating aligns with common industrial distribution schemes, and the 15 A rating suits branch circuits that require reliable protection without nuisance tripping on normal startup surges. When ordering, pairing this breaker with compatible Siemens accessories and mounting hardware will streamline installation and ensure consistent performance over time.
