1SDA070802R1 ABB E1.2N 1000 Ekip Dip LSI 3P Fixed Air Circuit Breaker

Why Choose the ABB E1.2N 1000 Ekip Dip LSI 3P Fixed Air Circuit Breaker?

The ABB 1SDA070802R1 is a high-performance SACE Emax 2 E1.2N air circuit breaker (ACB) designed for dependable protection and switching in low-voltage power distribution systems. Rated at 1000 A, this three-pole breaker incorporates an Ekip Dip LSI electronic trip unit providing long-time overload, selective short-time short-circuit and instantaneous short-circuit protection.

As part of the ABB SACE Emax 2 range, the E1.2N combines compact construction with strong short-circuit performance and straightforward electronic protection. The Ekip Dip LSI release uses DIP switches for configuration, allowing protection thresholds to be adapted to the distribution system without requiring a touchscreen interface.

This configuration is a three-pole fixed circuit breaker with front terminals. It provides an ultimate short-circuit breaking capacity of 66 kA at 400–440 V AC and 50 kA at 500–690 V AC, together with a short-time withstand current of 50 kA for 1 second.

Selective LSI Protection for Power Distribution

Air circuit breakers provide switching, isolation and fault protection at critical points in low-voltage distribution systems. The ABB SACE Emax 2 platform combines high short-circuit performance with electronic trip technology for dependable protection of switchboards, busbars, cables and connected equipment.

The Ekip Dip LSI trip unit fitted to this E1.2N configuration provides long-time overload, selective short-time short-circuit and instantaneous short-circuit protection. The additional short-time function compared with an LI release supports improved selectivity and coordination between upstream and downstream protective devices in multi-level electrical distribution systems.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Commercial building electrical distribution.
• Manufacturing and process facilities.
• Infrastructure and utility installations.
• Systems requiring selective short-circuit protection coordination.
• OEM switchboards and electrical distribution assemblies.
