1SDA071713R1 ABB E2.2H 2500 Ekip Dip LSIG 4p F HR Air Circuit Breaker 2500 A

Why Choose the ABB E2.2H 2500 Ekip Dip LSIG 4p F HR Air Circuit Breaker?

The ABB E2.2H 2500 Ekip Dip LSIG 4p F HR, order code 1SDA071713R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution systems, it combines a 2500 A rated uninterrupted current with an Ekip Dip LSIG electronic trip unit for comprehensive overload, selective short-circuit, instantaneous short-circuit and earth-fault protection.

The Ekip Dip LSIG release provides configurable electronic protection using straightforward DIP-switch settings. Its LSIG functionality covers long-time overload protection, selective short-time protection, instantaneous short-circuit protection and earth-fault protection, making this breaker particularly suitable for distribution systems where comprehensive fault protection and selective coordination are required.

The E2.2H performance level delivers a rated ultimate short-circuit breaking capacity of 100 kA at 440 V AC and a rated short-time withstand current of 85 kA for 1 s. Combined with four-pole fixed construction and rear horizontal terminals, the 1SDA071713R1 provides a robust solution for high-current industrial, commercial and infrastructure switchboards.
