Square D | EH14050 | Circuit Breaker | 50A | 1-Pole | 480V

Introducing Square D EH14050 — a 50A, 1-Pole circuit breaker designed for 480V systems. Built for maintenance, retrofit, and replacement projects, this exact-fit device provides reliable overcurrent protection when you need a direct, compatible match for your Square D panel setup.

Exact compatibility matters

In critical electrical environments, using the correct part number matters more than you might think. The EH14050 is identified by its part number as the primary reference for fit and ratings. Before ordering, verify that the breaker's amperage (50A), pole configuration (1-Pole), and voltage rating (480V) align with your panel and circuit requirements. The part number EH14050 is your best reference for compatibility.

Key specifications

Ideal use cases

Perfect for technicians conducting panel retrofits, replacements, or routine maintenance in 480V installations. Whether upgrading legacy protection or stocking a reliable spare for mission-critical equipment, this breaker ensures consistent protection without the guesswork of cross-referencing similar models.

Why choose this particular breaker

This isn’t a generic drop-in — it’s a precise, Square D solution engineered to meet the exacting standards of 480V single-pole protection. By sticking to the EH14050 part number, you minimize compatibility risks, reduce unexpected trips, and maintain smoother operation in your electrical infrastructure.

Practical guidance for best results

• Always confirm your system’s voltage rating and the required amperage before purchase. 50A at 480V indicates the level of protection for that specific circuit.
• Keep a known-good spare of EH14050 on hand for quick replacements during maintenance windows, minimizing downtime.
• Cross-check your panel’s documentation to ensure a single-pole configuration is appropriate for the target circuit within a 480V distribution scheme.
