Why Choose the ABB E1.2N 250 Ekip Dip LSIG 4p F F Air Circuit Breaker?
The ABB E1.2N 250 Ekip Dip LSIG 4p F F, order code 1SDA071323R1, is a compact and highly capable four-pole air circuit breaker (ACB) designed for switching and protection in low-voltage power distribution systems. As part of the advanced ABB SACE Emax 2 series, this fixed circuit breaker combines a 250 A rated current, high short-circuit performance and an Ekip Dip LSIG electronic protection release.
The integrated Ekip Dip LSIG electronic trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. This comprehensive protection package makes the breaker suitable for installations requiring effective selectivity, fault protection and earth-fault detection across industrial, commercial and infrastructure distribution networks.
With a rated operational voltage of up to 690 V AC, an ultimate short-circuit breaking capacity of 66 kA at 440 V AC and a rated short-time withstand current of 50 kA for 1 s, the E1.2N 250 provides robust protection in a compact Emax 2 frame. This version features a four-pole fixed configuration with front terminals, making it suitable for switchboards requiring a switched neutral conductor and accessible front connections.

Comprehensive Protection for Low-Voltage Distribution Systems
Air circuit breakers such as the ABB Emax 2 E1.2N provide switching and protection for low-voltage electrical distribution systems. By detecting overload, short-circuit and earth-fault conditions and interrupting fault current, the breaker helps protect switchboards, cables, busbars and connected electrical equipment while supporting safe and dependable system operation.
The Ekip Dip LSIG release provides four fundamental protection functions: long-time overload protection, short-time short-circuit protection, instantaneous short-circuit protection and earth-fault protection. The additional G function distinguishes this version from an LSI-equipped breaker and enables earth-fault detection alongside conventional overcurrent protection, making it particularly useful in distribution systems requiring comprehensive fault protection.
Typical Applications
- Low-voltage main and sub-distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Three-phase four-wire distribution networks.
- Transformer secondary-side protection.
- Manufacturing and process industry installations.
- Infrastructure and utility distribution systems.
- Power distribution panels requiring earth-fault protection and switched neutral conductors.
