1SDA100230R1 ABB XT4S 250 Ekip Dip LIG 250 A 4-Pole MCCB

Why Choose the ABB 1SDA100230R1 XT4S 250 Ekip Dip LIG Circuit Breaker?

The ABB 1SDA100230R1 is a Tmax XT4S 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 electronic overload, instantaneous short-circuit and ground-fault protection for AC low-voltage electrical distribution systems.

As part of the ABB Tmax XT range, the XT4 platform combines compact construction with configurable 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, severe short circuits and earth-fault conditions.

With a rated current and rated uninterrupted current of 250 A, a rated operational voltage of up to 690 V AC and an S short-circuit performance level, the 1SDA100230R1 is suited to demanding switchboards and distribution systems. Its rated service short-circuit breaking capacity reaches 50 kA at 415 V AC, while its fixed four-pole construction and front terminals facilitate integration into low-voltage electrical assemblies.

Reliable Electronic Protection for Power Distribution

Moulded case circuit breakers equipped with electronic trip units monitor current within the protected circuit and interrupt the supply when configured protection thresholds are exceeded. The ABB Ekip Dip platform provides adjustable electronic protection that can be coordinated with the requirements of cables, feeders and electrical equipment in modern low-voltage distribution systems.

The LIG configuration combines long-time protection against sustained overloads, instantaneous protection against severe short circuits and ground-fault protection for earth-fault conditions. Combined with the XT4S 250 platform, four-pole construction and 50 kA service breaking capacity at 415 V AC, these functions make the 1SDA100230R1 suitable for robust circuit protection in industrial, commercial and infrastructure electrical installations.
