ABB E1N 1250A 240V 3-Pole Air Circuit Breaker for Industrial and Commercial Power Distribution

Product description
Shipping

The ABB E1N 1250A 240V 3-Pole Air Circuit Breaker is engineered for the heavy-duty demands of modern industrial and commercial power distribution. Built to protect low-voltage networks, this 3-pole device delivers dependable fault protection and precise switching for main feeders, switchboards, and critical circuits, helping your facility run with fewer unexpected outages.

Why this E1N breaks through the standard protection

  • High-capacity protection: With a 1250A current rating and a robust air-break design, it handles substantial fault currents common in large facilities, enabling rapid isolation to minimize downtime and equipment damage.
  • Three-phase reliability: The 3-pole configuration ensures balanced protection across all phases, preserving power quality and reducing the risk of phase imbalance affecting sensitive loads.
  • Low-voltage, scalable protection: Rated for 240V, it fits neatly into typical low-voltage distribution schemes found in industrial and commercial settings, from manufacturing floors to data centers and large office complexes.
  • Adjustable trip settings: Tailor protection to your network by coordinating with downstream devices and accommodating specific load characteristics, improving selectivity and reducing nuisance trips.
  • Durable, maintenance-friendly design: ABB’s rugged air circuit breaker platform offers long service life in demanding environments, with straightforward inspection and maintenance routines to keep it functioning reliably.

Ideal use scenarios

  • Main incoming feeders at large switchboards that serve heavy-load equipment and critical systems
  • Industrial facilities where fast fault clearance protects motors, drives, and process control gear
  • Commercial buildings with large electrical distribution networks requiring robust, configurable protection
  • Applications needing precise coordination with other protective devices to prevent cascading trips

How it supports safer, more efficient power distribution

The E1N’s design targets rapid fault elimination while preserving as much usable power as possible for non-faulted loads. By isolating faults quickly, it minimizes arc fault energy, protects downstream equipment, and helps reduce downtime during maintenance or unexpected events. Its adjustable trip settings empower engineers to align protection with the specific characteristics of their distribution topology, improving system resilience without compromising on operational efficiency.
