1SDA071866R1 ABB E6.2H 4000 Ekip Touch LSIG 4P Air Circuit Breaker

Why Choose the ABB E6.2H 4000 Ekip Touch LSIG 4P Air Circuit Breaker?

The ABB 1SDA071866R1 is a high-performance SACE Emax 2 E6.2H air circuit breaker (ACB) rated at 4000 A, engineered for protection and switching in demanding low-voltage power distribution systems. Part of the ABB SACE Emax 2 series, this fixed four-pole breaker combines substantial current capacity with the advanced Ekip Touch LSIG electronic trip unit.

The Ekip Touch LSIG solid-state release provides long-time overload, short-time selective, instantaneous short-circuit and earth-fault protection. Its touchscreen interface supports intuitive configuration and monitoring, while the Ekip platform provides a flexible foundation for communication, automation and power-management functions in sophisticated electrical installations.

With a rated uninterrupted current of 4000 A, rated operational voltage up to 690 V AC and ultimate short-circuit breaking capacity of 100 kA across key AC operating voltages up to 690 V AC, the E6.2H provides robust protection for high-current networks. This version is a fixed four-pole breaker with rear flat horizontal terminals and is fitted with four auxiliary contacts plus circuit-breaker open/closed position indication.
