1SDA072234R1 ABB E1.2N 1600 Ekip Touch LI 3p WMP Air Circuit Breaker

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

The ABB E1.2N 1600 Ekip Touch LI 3p WMP, order code 1SDA072234R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for protection and switching in low-voltage AC power distribution systems. As part of the ABB Emax 2 E1.2 series, this three-pole breaker combines a rated current of 1600 A with the advanced Ekip Touch LI electronic protection release.

The Ekip Touch LI trip unit provides long-time overload and instantaneous short-circuit protection, with settings and operating information accessible through its touchscreen interface. This protection combination is well suited to distribution applications requiring configurable electronic protection without the additional short-time or earth-fault functions of LSIG releases.

This version is a withdrawable moving part (WMP) for compatible Emax 2 fixed parts. With a 690 V AC rated voltage and an ultimate short-circuit breaking capacity of 66 kA at 400–440 V AC, the E1.2N 1600 provides robust protection for demanding industrial, commercial and infrastructure power-distribution installations.

Reliable Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect high-current electrical distribution circuits against damaging overloads and short circuits. The Ekip Touch LI release combines adjustable long-time overload protection with instantaneous short-circuit protection, allowing the breaker to disconnect a circuit when electrical conditions exceed its configured protection thresholds.

The withdrawable E1.2 construction is particularly useful in switchboards where inspection, maintenance and equipment replacement need to be carried out efficiently. The moving part interfaces with the appropriate Emax 2 fixed part, while the electronic Ekip Touch platform provides intuitive touchscreen configuration for protection settings and circuit-breaker operation.

Typical Applications

• Industrial low-voltage power distribution switchboards.
• Main incoming and feeder circuit protection.
• Commercial building electrical distribution systems.
• Manufacturing and process-industry switchgear.
• Transformer secondary distribution systems.
• Infrastructure and utility electrical installations.
• High-current three-phase AC distribution networks.
• Withdrawable switchgear requiring electronic LI protection.
