Why Choose the ABB XT5N 400 Ekip Dip LS/I 400 3P FF UL/CSA 1SDA102449R1?
The ABB 1SDA102449R1 is a SACE Tmax XT5N moulded-case circuit breaker designed for dependable protection of low-voltage AC distribution systems. Rated at 400 A, this three-pole breaker combines ABB's compact XT5 frame with an Ekip Dip LS/I solid-state electronic trip unit, fixed installation and front terminals.
The Ekip Dip LS/I trip unit provides long-time overload protection, short-time short-circuit protection and instantaneous short-circuit protection. Its electronic protection architecture allows the breaker to be coordinated with downstream equipment while providing rapid response to severe fault currents.
Designed for UL/CSA applications, the XT5N has an N interruption-performance level rated at 35 kA at 480 V AC. The combination of a 400 A frame rating, three-pole construction and fixed front-terminal configuration makes the 1SDA102449R1 suitable for industrial, commercial and OEM power distribution assemblies.
