1SDA071961R1 ABB E6.2V/f 4000 Ekip Dip LI 4p FHR Air Circuit Breaker

Why Choose the ABB E6.2V/f 4000 Ekip Dip LI 4p FHR Air Circuit Breaker?

The ABB E6.2V/f 4000 Ekip Dip LI 4p FHR, order code 1SDA071961R1, is a high-performance SACE Emax 2 air circuit breaker designed for reliable protection and switching in demanding low-voltage power distribution systems. With a 4000 A rated uninterrupted current, four-pole full-size neutral configuration and Ekip Dip LI electronic trip unit, it provides dependable overload and instantaneous short-circuit protection for high-current electrical installations.

As part of the ABB SACE Emax 2 E6.2V/f range, this fixed air circuit breaker combines very high short-circuit performance with straightforward electronic protection. The Ekip Dip LI release provides long-time overload and instantaneous short-circuit protection, while the full-size neutral pole makes the breaker suitable for four-wire distribution systems requiring full neutral-current capability.

The E6.2V/f performance level provides an ultimate short-circuit breaking capacity of 150 kA at 400–415 V AC and up to 100 kA at 690 V AC. The breaker uses rear horizontal terminals and is supplied with four auxiliary change-over contacts and open/closed position indication, supporting effective integration into high-power switchboards.
