1SDA070885R1 ABB E1.2N 1600 Ekip Touch LSI 3p F F Air Circuit Breaker

Why Choose the ABB E1.2N 1600 Ekip Touch LSI 3p F F Air Circuit Breaker?

The ABB E1.2N 1600 Ekip Touch LSI 3p F F, order code 1SDA070885R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for protection and switching in demanding low-voltage AC power distribution systems. Part of the advanced ABB Emax 2 E1.2 series, it combines a compact 1600 A frame with an Ekip Touch electronic trip unit for precise and configurable overcurrent protection.

This model is a fixed, three-pole circuit breaker with front terminals equipped with an Ekip Touch LSI solid-state electronic release. Its LSI protection functions provide long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection, enabling effective protection and selectivity for cables, busbars, transformers and downstream distribution equipment.

With a rated uninterrupted current of 1600 A, rated voltage of 690 V AC and a rated ultimate short-circuit breaking capacity of 66 kA at 400 V AC, the E1.2N 1600 is engineered for high-current distribution systems with substantial prospective fault levels. Four auxiliary change-over contacts and circuit-breaker open/closed position indication support integration into switchboard signalling and control systems.

Advanced Selective Protection for Power Distribution

Air circuit breakers such as the ABB Emax 2 E1.2N protect low-voltage electrical networks by automatically interrupting current when dangerous overcurrent conditions occur. The Ekip Touch LSI electronic release provides separate long-time, short-time delayed and instantaneous protection functions, allowing protection settings to be coordinated with upstream and downstream devices while safeguarding conductors and connected equipment.

The E1.2N performance class combines high short-circuit capability with the compact architecture of the Emax 2 E1.2 frame. Its adjustable Ekip Touch protection, fixed front-terminal construction and auxiliary signalling capability make the 1SDA070885R1 particularly suitable for main incomers, high-current feeders and selective industrial power-distribution systems.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Main incomer and high-current feeder protection.
• Selective distribution and circuit-protection systems.
• Commercial building electrical distribution.
• Manufacturing and process plant switchgear.
• Infrastructure and utility distribution installations.
• OEM switchboards and power-distribution panels.
