Square D EH14020HID 20A 1-Pole 480 V Circuit Breaker

Meet the Square D EH14020HID: a compact, high‑voltage circuit breaker engineered for demanding industrial and commercial panels. With a 20 A current rating and a single pole, this breaker delivers precise overcurrent protection for 480 V distribution circuits, helping keep equipment safe and uptime high. Part Number EH14020HID clearly identifies the exact model you need for reliable replacements and panel upgrades.

Why this 20A, 1‑Pole 480 V breaker stands out

• High-voltage protection rated for 480 V systems, making it a solid choice for industrial feeders and panelboards in commercial facilities.
• Compact, single-pole design provides focused protection for individual hot circuits while minimizing footprint in crowded enclosures.
• Trusted Square D engineering quality designed to handle everyday industrial loads with predictable trip characteristics and durable construction.
• Clear part identification EH14020HID for easy ordering, stocking, and compatibility with EH‑series configurations.
• Panel‑level compatibility intended for use with Square D panels that accept EH‑style breakers, supporting straightforward replacement or cross‑reference within your electrical distribution system.

Ideal use cases

• Protection for a single high‑voltage branch circuit feeding motors, conveyors, or processing equipment in manufacturing and warehousing environments.
• Upgrades or replacements in industrial panels where 480 V distribution is standard and space is at a premium.
• Temporary or permanent installations in facilities that require dependable 20 A protection without increasing panel complexity.

How it solves real-world challenges

• Prevents electrical faults from spreading through critical 480 V circuits by interrupting fault currents promptly, reducing damage to downstream equipment.
• Streamlines maintenance with a clearly identifiable part number, making stocking and ordering faster and less error-prone.
• Supports reliable panel planning by delivering a predictable, standardized protection point for individual feeders in complex electrical rooms.

Installation and maintenance tips

To ensure optimal performance, verify that your panel accepts EH‑series breakers and follow current electrical codes during installation. Use the correct torque on terminal connections and inspect the device after installation for firm seating and proper alignment. Replace the breaker if you observe signs of wear, overheating, or repeated nuisance trips rather than attempting field repairs.
