1SDA071512R1 ABB E1.2N 1600 Ekip Dip LSI 4p F F Air Circuit Breaker

Why Choose the ABB E1.2N 1600 Ekip Dip LSI 4p F F Air Circuit Breaker?

The ABB E1.2N 1600 Ekip Dip LSI 4p F F, order code 1SDA071512R1, is a high-performance four-pole air circuit breaker (ACB) designed for protection and switching in low-voltage power distribution systems. As part of the advanced ABB SACE Emax 2 series, it combines a 1600 A rated current with electronic LSI protection and high short-circuit breaking performance for demanding industrial, commercial and infrastructure installations.

This fixed circuit breaker is equipped with the Ekip Dip LSI electronic trip unit, providing long-time overload, short-time selective short-circuit and instantaneous short-circuit protection. Protection thresholds are adjustable using DIP switches, allowing the breaker characteristics to be configured for the requirements of the electrical distribution system while supporting effective coordination with other protective devices.

With a rated operational voltage of up to 690 V AC, four-pole construction and an ultimate short-circuit breaking capacity of 66 kA at 380–440 V AC, the 1SDA071512R1 provides robust protection for substantial low-voltage installations. Its fixed configuration and front terminals make it suitable for permanent integration into electrical switchboards and power distribution assemblies.

Selective Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect high-current electrical distribution systems against overloads and short circuits. By automatically interrupting the circuit when configured protection thresholds are exceeded, the breaker helps safeguard cables, busbars, switchgear and connected equipment while reducing the risk of damage caused by electrical faults.

The Ekip Dip LSI trip unit combines long-time overload, short-time selective and instantaneous short-circuit protection. The addition of the short-time protection function allows greater flexibility when coordinating upstream and downstream protective devices, making the E1.2N particularly suitable for distribution systems where selectivity and continuity of service are important.
