Why Choose the ABB XT7S 800 Ekip Dip LIG In=800A 4p F F Circuit Breaker?
The ABB XT7S 800 Ekip Dip LIG In=800A 4p F F, order code 1SDA101166R1, is a high-performance four-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range. Designed for transformer, generator and installation protection, it combines an 800 A rated uninterrupted current with an Ekip Dip LIG electronic trip unit for dependable protection in demanding low-voltage distribution systems.
The Ekip Dip LIG solid-state electronic release provides overload, instantaneous short-circuit and ground-fault protection functions. Its adjustable settings enable the protection characteristics to be coordinated with the electrical installation, helping safeguard conductors, switchgear and connected equipment against damaging overcurrent and earth-fault conditions.
The XT7S version provides a rated ultimate short-circuit breaking capacity of 50 kA at 400 V AC, 50 Hz. Its four-pole fixed construction, front terminals, bolt-connected main circuit and lever operating mechanism make the 1SDA101166R1 a practical choice for high-current switchboards and power distribution assemblies.
