Detailed Description

The ABB E2.2N 2500 (part no. 1SDA071691R1) is a high-performance fixed four-pole air circuit breaker designed for heavy-duty industrial and utility applications. Engineered by ABB’s SACE Emax2 range, this breaker provides reliable protection and switching for large electrical installations.

Key features:

• Rated current: 2 500 A (In) – ideal for large power distribution panels. 

• Four-pole fixed configuration with rear-horizontal terminals and bolt type connections (tightening torque 70 N·m) for solid installation.

• High breaking capacity: 66 kA short-circuit service breaking capacity (Ics) at up to 690 V AC, making it suitable for demanding installations and high fault levels. 

• Rated operational voltage up to 690 V AC and insulation voltage up to 1 000 V AC. 

• Innovative release mechanism: EKIP DIP LI electronic trip module which offers adjustable protection and diagnostics. 

• Compact yet robust dimensions: approx. 366 mm (W) x 371 mm (H) x 270 mm (D), net weight approx. 53 kg. 

• Recyclability and compliance: part of ABB EcoSolutions, with RoHS compliance and designed for closed-loop resource recovery. 

Benefits to your facility:

• Enables safe switching and protection of large feeders, transformer mains or generator supplies.

• High fault tolerance reduces risk of downtime or equipment damage under fault conditions.

• Rear-horizontal bolt connections simplify panel layout and wiring in modern switchgear frames.

• The EKIP electronic trip unit allows easier calibration, monitoring and integrating with smart systems if used.

• Built with a trusted global brand (ABB) so you are backed by support, spares and worldwide supply.

Applications:
Perfect for industrial plants, commercial high-rise buildings, data centres, power generation, large infrastructure or utility switchrooms where 2 500 A class protection is required.
