1SDA073638R1 ABB E2.2S 250 Ekip Dip LI 4p F HR Emax 2 Air Circuit Breaker

Why Choose the ABB E2.2S 250 Ekip Dip LI 4p F HR Emax 2 Air Circuit Breaker?

The ABB E2.2S 250 Ekip Dip LI 4p F HR, order code 1SDA073638R1, is a 250 A four-pole fixed air circuit breaker from the ABB SACE Emax 2 range. Designed for low-voltage power distribution, it combines the E2.2 frame with S-level breaking performance, rear horizontal terminals and the electronic Ekip Dip LI trip unit.

This Emax 2 circuit breaker provides a rated ultimate short-circuit breaking capacity of 85 kA at 400/415 V AC and 66 kA at 690 V AC. Its rated short-time withstand current is 66 kA for 1 s, providing robust fault-handling performance for industrial, commercial and infrastructure distribution systems.

The fitted Ekip Dip LI electronic protection release provides adjustable long-time overload protection (L) and instantaneous short-circuit protection (I). Protection settings are configured using DIP switches, providing straightforward adjustment while retaining dependable electronic protection for the connected electrical distribution system.

Reliable Electronic Protection for Low-Voltage Distribution

The ABB E2.2S 250 combines the switching and fault-interruption capabilities of an Emax 2 air circuit breaker with the electronic protection functions of the Ekip Dip LI release. The long-time protection function responds to sustained overload conditions, while the instantaneous function provides rapid operation when high short-circuit currents are detected.

With an ultimate breaking capacity of 85 kA at 400/415 V AC, the breaker is suitable for distribution systems with substantial prospective fault levels. Its fixed four-pole construction and rear horizontal terminals provide a practical arrangement for permanent installation in compatible low-voltage switchboards and power distribution assemblies.

Typical Applications

• Industrial low-voltage switchboards.
• Main incoming and distribution circuit protection.
• Four-pole power distribution systems.
• Commercial building electrical distribution.
• Manufacturing and process facilities.
• Infrastructure power distribution.
• Generator and transformer distribution systems.
• Installations requiring adjustable electronic overload and instantaneous short-circuit protection.
