1SDA072905R1 ABB E2.2N 1000 Ekip Touch LSI 4P WMP Air Circuit Breaker

Why Choose the ABB E2.2N 1000 Ekip Touch LSI 4p WMP Air Circuit Breaker?

The ABB E2.2N 1000 Ekip Touch LSI 4p WMP, order code 1SDA072905R1, is a high-performance four-pole air circuit breaker moving part from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution systems, it combines a 1000 A rated uninterrupted current with the advanced Ekip Touch LSI electronic trip unit for precise overload and short-circuit protection.

The Ekip Touch LSI release provides long-time (L), selective short-time (S) and instantaneous (I) protection functions. Adjustable protection settings enable effective coordination with downstream protective devices, while the Ekip Touch interface provides an intuitive platform for configuring protection parameters and monitoring the breaker within modern electrical distribution systems.

The E2.2N frame provides an ultimate short-circuit breaking capacity of 66 kA across its specified AC voltage range up to 690 V AC. Its withdrawable moving-part construction supports convenient servicing and maintenance, while the four-pole configuration incorporates a neutral pole rated at 100% of the rated uninterrupted current.

Advanced Selective Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 protect high-current low-voltage electrical systems against overloads and short circuits. The Ekip Touch LSI release continuously monitors circuit current and provides adjustable long-time, selective short-time and instantaneous protection, helping safeguard cables, transformers, switchgear and connected equipment.

Selective short-time protection is particularly useful in distribution networks containing multiple protective devices because it supports coordinated fault clearing between upstream and downstream breakers. Combined with the E2.2N frame's 66 kA breaking capacity and withdrawable architecture, the 1SDA072905R1 provides dependable protection with convenient maintenance access for modern industrial and commercial switchboards.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Transformer and installation protection.
• Commercial and infrastructure electrical distribution.
• Manufacturing and process plant switchgear.
• Selective distribution networks requiring coordinated protection.
• Four-wire low-voltage electrical systems.
• Withdrawable switchboards requiring convenient breaker maintenance.
