Detailed Description

The ABB E2.2N 2500 (catalog no. 1SDA071061R1) is a high‑capacity fixed air circuit breaker from ABB’s SACE Emax2 line, designed for three‑pole (3P) installations where robust protection and switching performance are essential.

Key Features & Specifications:

• Rated current: 2,500 A (In) for heavy‑duty power distribution applications. 

• Rated service short‑circuit breaking capacity (Ics) and ultimate breaking capacity (Icu): 66 kA across 220 V to 690 V. 

• Fixed type, 3‑pole configuration (no neutral pole) with rear‑horizontal bolt‑type main terminals—optimized for modern switchgear layouts. 

• Release unit: EKIP DIP LI electronic trip module (version “F”), offering adjustable protection and diagnostics. 

• Rated insulation voltage (Ui): AC 1000 V; Rated operational voltage: up to 690 V AC. 

• Dimensions / weight: width approx. 276 mm, height approx. 371 mm, depth approx. 270 mm; net weight 41 kg. 

• Eco‑design: part of ABB’s EcoSolutions initiative, designed for circular economy and higher recyclability. 

Benefits for your installation:

• Reliable switching and protection for large feeders, generator sets or transformer outputs in industrial, commercial or utility installations.

• High fault‑current tolerance helps reduce risk of downtime and equipment damage in demanding electrical environments.

• Rear‑horizontal bolt connection style simplifies integration in compact, modular switchgear systems.

• The electronic trip unit offers better monitoring and configuration flexibility, benefiting systems where diagnostics or adjustable protection are needed.

• Backed by ABB’s global support and strong component ecosystem for long‑term serviceability.

Typical Applications:

• Main or sub‑main distribution boards in factories, power plants, large infrastructure or data centers.

• Protection of high‑current feeders or switchgear segments where 2,500 A class capacity is required.

• Integration into modern low‑voltage switchgear systems where compactness and high performance matter.

What’s Included / What to Check:

• ABB E2.2N 2500 ACB (3P) part number 1SDA071061R1.

• Ensure compatibility with your switchgear frame (fixed type, rear bolts).

• Verify the correct setting, coordination and terminal connection requirements (bolt size, torque ~70 N·m). 

• Installation must comply with relevant local regulations and be done by qualified personnel.

Important Notes:

• Always confirm the short‑circuit rating, feeder load, and coordination with upstream/downstream protection devices.

• Ensure adequate clearance, cooling and installation conditions as per ABB’s datasheet.

• Availability of accessories (auxiliary contacts, shunt trips, communication modules) may affect total cost and integration.
