Why Choose the ABB E6.2V 4000 Ekip Touch LI 4p FHR Air Circuit Breaker?
The ABB E6.2V 4000 Ekip Touch LI 4p FHR, order code 1SDA071874R1, is a high-performance four-pole air circuit breaker (ACB) designed for demanding low-voltage power distribution systems. Part of the ABB SACE Emax 2 family, it combines a 4000 A rated uninterrupted current with the advanced Ekip Touch LI electronic protection release and the exceptional short-circuit capability of the E6.2V frame.
The Ekip Touch LI electronic trip unit provides long-time overload and instantaneous short-circuit protection through an intuitive touch interface. This LI configuration is well suited to applications requiring adjustable electronic protection and advanced monitoring without integrated short-time or earth-fault protection functions.
Rated for operation at up to 690 V AC, the E6.2V 4000 provides an ultimate short-circuit breaking capacity of 150 kA at 400–440 V AC, 130 kA at 500–525 V AC and 100 kA at 690 V AC. Its 100 kA short-time withstand current further supports demanding high-current distribution applications. This version is supplied as a fixed four-pole breaker with rear flat horizontal terminals.

High-Performance LI Protection for Power Distribution
The ABB E6.2V frame is engineered for high-current distribution systems where exceptional short-circuit interruption capability is required. With 150 kA Icu at 400–440 V AC and 100 kA Icu at 690 V AC, the breaker can protect major switchboards, busbars, cables and connected equipment in installations with substantial prospective fault currents.
The Ekip Touch LI release combines long-time overload protection with instantaneous short-circuit protection. Its overload setting can be adjusted across 1600–4000 A, while instantaneous protection covers 6000–60000 A. This makes the 1SDA071874R1 particularly suitable where configurable electronic LI protection and very high breaking capacity are required without integrated short-time or earth-fault protection.
