1SDA100200R1 ABB XT4N 250 Ekip Dip LIG 250 A 4-Pole MCCB

Why Choose the ABB 1SDA100200R1 XT4N 250 Ekip Dip LIG Circuit Breaker?

The ABB 1SDA100200R1 is a Tmax XT4N 250 moulded case circuit breaker (MCCB) equipped with an Ekip Dip LIG electronic trip unit. Rated at 250 A and configured as a 4-pole fixed circuit breaker with front terminals, it provides dependable electronic protection for AC low-voltage electrical distribution systems.

As part of the ABB Tmax XT range, the XT4 platform combines compact construction with electronic protection for industrial and commercial power distribution. The Ekip Dip LIG trip unit provides long-time, instantaneous and ground-fault protection functions, helping protect cables, feeders and electrical equipment against overloads, short circuits and ground faults.

With a rated current of 250 A, a rated operational voltage of up to 690 V AC and an N performance level providing 36 kA breaking capacity at 415 V AC, the 1SDA100200R1 is suitable for demanding switchboards and distribution systems. Its fixed four-pole construction and front terminals enable straightforward integration into low-voltage electrical assemblies.
