Siemens | E42B015 | Circuit Breaker | 15A | 2-Pole | 480V

When your system runs on 480V and reliability matters, the Siemens E42B015 circuit breaker delivers precise overcurrent protection with two poles that disconnect both live conductors together. This unit is built for maintenance, retrofit, and replacement projects where exact specifications drive safety and performance.

Key specifications at a glance

• Amperage: 15A
• Poles: 2-Pole
• Voltage rating: 480V
• Part reference: E42B015

Notes: Confirm fit and ratings before ordering. The part number is the best reference for compatibility with your panel and system.

Why this model fits demanding industrial panels

The E42B015 is more than a generic breaker—it's a precise match for Siemens panels and assemblies that specify a 2-pole, 15A unit at 480V. Using the exact part number minimizes trial-and-error, reduces downtime, and helps maintain code-compliant protection for equipment and operators.

Ideal use scenarios

• Maintenance and retrofit in manufacturing lines powered by 480V services
• Replacement where the existing panel requires an E42B015-type device
• Electrical rooms and control cabinets needing reliable, fast-disconnect protection
• Portable or temporary setups where a quick, exact-match breaker is beneficial

Practical installation tips

• Verify panel compatibility by the exact part number (E42B015) before purchase.
• Inspect the breaker's condition and torque on terminals during installation.
• Keep a spare E42B015 on hand for planned maintenance to minimize downtime.

With Siemens engineering behind it, this 15A, 2-pole, 480V circuit breaker helps you protect critical equipment, reduce nuisance trips, and keep your electrical infrastructure robust and compliant.
