Why Choose the ABB XT5N 400 Ekip Dip LSI 400A 4P Circuit Breaker?
The ABB XT5N 400 Ekip Dip LSI In=400 4P F F 1SDA100400R1 is a fixed four-pole SACE Tmax XT5 moulded case circuit breaker designed for dependable protection of low-voltage AC power-distribution systems. It combines the XT5N 400 frame with a 400 A Ekip Dip LSI solid-state electronic release.
The Ekip Dip LSI trip unit provides long-time, short-time and instantaneous protection against overload and short-circuit conditions. Long-time protection is adjustable over 0.4–1 × In, while the short-time and instantaneous thresholds are configurable over 1–10 × In, providing flexibility for selective protection and coordination within electrical distribution systems.
The 1SDA100400R1 is supplied as a fixed four-pole breaker with front terminals. Its XT5N interruption-performance class provides an ultimate short-circuit breaking capacity of 36 kA at 415 V AC, making it suitable for industrial, commercial and infrastructure applications requiring four-pole electronic circuit protection.
