1SDA100235R1 ABB XT4H 250 Ekip Dip LSI 250 A 3-Pole MCCB

Why Choose the ABB 1SDA100235R1 XT4H 250 Ekip Dip LSI Circuit Breaker?

The ABB 1SDA100235R1 is a Tmax XT4H 250 moulded case circuit breaker (MCCB) equipped with an Ekip Dip LSI electronic trip unit. Rated at 250 A and configured as a 3-pole fixed circuit breaker with front terminals, it provides dependable electronic overload and short-circuit 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 LSI trip unit provides long-time, short-time and instantaneous protection functions, helping protect cables, feeders and electrical equipment against sustained overloads and different levels of short-circuit current.

With a rated current and rated uninterrupted current of 250 A, a rated operational voltage of 690 V AC and the high-performance H breaking-capacity class, the 1SDA100235R1 is suited to demanding distribution systems. It provides a rated service and ultimate short-circuit breaking capacity of 70 kA at 415 V AC, while its fixed three-pole construction and front terminals facilitate integration into switchboards and electrical assemblies.

High-Performance 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 uses adjustable protection settings to help coordinate circuit protection with the requirements of cables, feeders and electrical equipment in modern low-voltage distribution systems.

The LSI configuration combines long-time protection against sustained overloads, short-time protection for selective fault coordination and instantaneous protection against severe short circuits. Combined with the XT4H 250 platform and its 70 kA breaking capacity at 415 V AC, these functions make the 1SDA100235R1 particularly suitable for installations where high prospective fault currents require robust circuit protection.
