Why Choose the ABB E4.2V 2000 Ekip G Hi-Touch LSIG 4p FHR Air Circuit Breaker?
The ABB E4.2V 2000 Ekip G Hi-Touch LSIG 4p FHR, order code 1SDA071740R1, is a high-performance four-pole Emax 2 air circuit breaker designed for protection, control and energy management in demanding low-voltage electrical distribution systems. Part of the ABB SACE Emax 2 E4.2 series, this fixed circuit breaker combines a 2000 A rated current with the advanced Ekip G Hi-Touch electronic trip unit.
The E4.2V performance level provides a high short-circuit breaking capability, with a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC. Its Ekip G Hi-Touch LSIG protection unit provides sophisticated long-time, short-time, instantaneous and earth-fault protection functions, making the breaker suitable for critical power-distribution and generator-protection applications where precise monitoring and selective protection are required.
This version is a four-pole fixed circuit breaker with rear flat horizontal (FHR) terminals. It has a rated operational voltage of up to 690 V AC and an E4.2V short-time withstand capability of 100 kA for 1 s, providing robust protection for high-current industrial installations, infrastructure and power-generation systems.
