Schneider Electric EHB41020 Circuit Breaker, 20A, 1-Pole, 277V

Meet the Schneider Electric EHB41020 — a rugged, industrial-grade circuit breaker designed for reliable overcurrent protection in commercial and industrial electrical systems. With a 20 A rating, 1 pole, and 277 V operation, this breaker is built to safeguard circuits that power lighting, control equipment, and other 277-volt loads in demanding environments.

The EHB41020 is intended for industrial service, maintenance, and replacement projects. Use the part number to confirm compatibility for your application, ensuring a precise fit within your panel or enclosure. If you’re unsure, we’re ready to help you verify compatibility by part number and application requirements.

• Amperage: 20 A
• Poles: 1
• Voltage: 277 V
• Part number: EHB41020
• Applications: industrial electrical service, maintenance, and replacement projects requiring single-pole protection for 277 V circuits

Why choose this Schneider Electric breaker? It’s designed to deliver consistent protection for critical 277 V circuits, helping prevent damage from overloads and short circuits while fitting into standard industrial panel configurations that require a 1-pole, 20 A unit. Its part-number specificity (EHB41020) helps ensure you’re selecting the exact component your system was designed to use, reducing compatibility risk during maintenance or upgrades.

Use scenarios include replacing worn breakers in commercial lighting feeders, protecting small machinery on 277 V feeds, or stocking spare parts for routine maintenance. The 1-pole, 20 A profile makes it ideal for circuits where only a single path to ground or neutral needs protection, while the 277 V rating aligns with typical distribution in many industrial environments.
