Westhinghouse EH3015 - 15A, 3-Pole, Circuit Breaker

The Westhinghouse EH3015 15A, 3-Pole Circuit Breaker delivers dependable overcurrent protection for demanding 3-phase electrical systems. Designed for use in panelboards, switchboards, and control panels, this unit provides reliable safeguarding in industrial, commercial, and OEM environments where uptime and safety are critical.

• Current rating: 15A — precise protection for common 3-phase circuits.
• Poles: 3-Pole — protects all three phases simultaneously, helping prevent unbalanced faults and nuisance trips.
• Configuration: Circuit Breaker type engineered for seamless integration into existing distribution equipment.
• Applications: Ideal for distribution panels and motor control centers, as well as control panels in manufacturing facilities and commercial buildings.

Why the 3-Pole design matters

In three-phase systems, a single fault can affect multiple conductors. The EH3015’s 3-Pole configuration ensures synchronized trip across all phases, delivering coordinated protection for motors, drives, and other three-phase loads. This reduces the risk of lingering faults and protects equipment from damage caused by imbalanced currents.

Ideal use cases

• Industrial facilities with three-phase motors and conveyors requiring robust, automatic protection.
• Commercial switchboards and distribution panels that demand reliable trip performance and easy maintenance.
• OEM equipment needing a dependable, compact 3-pole protector as part of a broader control system.

What sets it apart

Beyond basic protection, the EH3015 emphasizes consistent trip behavior across all three phases, simplifying diagnostics and reducing downtime. Its steadfast performance across a range of environments makes it a practical choice for facilities that rely on motor-driven processes and critical loads.

Practical tips for use

• Verify that your enclosure accepts 3-Pole breakers and that the 15A rating matches the circuit’s design load.
• Pair this breaker with correctly rated conductors and follow panel manufacturer mounting and labeling guidelines to maintain reliable trip performance.
• Use in distribution panels or motor control centers where coordinated protection across phases is essential for safe operation.

For projects requiring sturdy, three-phase protection with straightforward installation, the Westhinghouse EH3015 15A, 3-Pole Circuit Breaker offers precise current limiting, reliable tripping, and compatibility with a broad range of panel and control applications.
