1SDA073023R1 ABB E2.2S 2000 Ekip Dip LSIG 4p WMP Air Circuit Breaker

Why Choose the ABB E2.2S 2000 Ekip Dip LSIG 4p WMP Air Circuit Breaker?

The ABB 1SDA073023R1 is a high-performance SACE Emax 2 E2.2S air circuit breaker rated at 2000 A, designed for protection, switching and isolation in demanding low-voltage power distribution systems. This four-pole withdrawable moving part incorporates the Ekip Dip LSIG electronic trip unit, providing long-time, short-time, instantaneous and ground-fault protection.

As part of the ABB SACE Emax 2 range, the E2.2S combines substantial current capacity with high short-circuit performance and configurable electronic protection. The Ekip Dip LSIG release uses straightforward DIP-switch adjustment and provides the principal protection functions required for selective and comprehensive protection of industrial and commercial distribution networks.

With a rated uninterrupted current of 2000 A and a four-pole configuration, the E2.2S is engineered for high-current switchboards and feeders. The S performance class provides an ultimate short-circuit breaking capacity of up to 85 kA at 400/415 V AC, while the withdrawable moving-part design facilitates inspection, maintenance and replacement in applications where serviceability and system availability are important.

Comprehensive LSIG Protection for High-Current Distribution

The Ekip Dip LSIG release provides four key protection functions for low-voltage electrical networks. Long-time protection responds to sustained overloads, short-time protection supports selective coordination, instantaneous protection responds rapidly to severe short circuits, and the ground-fault function protects against earth-fault current conditions.

Combined with the high-current E2.2S frame, these functions make the 1SDA073023R1 well suited to main distribution circuits where fault selectivity and comprehensive electronic protection are required. The withdrawable configuration also enables the moving part to be removed from its corresponding fixed part, supporting efficient maintenance and reduced switchboard downtime.

Typical Applications

• Main low-voltage switchboards and distribution boards.
• Industrial power distribution systems.
• Manufacturing plants and process facilities.
• Large commercial buildings and infrastructure installations.
• Transformer secondary and main incoming protection.
• High-current feeders requiring selective short-circuit and integrated ground-fault protection.
