1SDA101281R1 ABB XT7L 1600 Ekip Dip LIG In=1600A 4p F F Circuit Breaker

Why Choose the ABB XT7L 1600 Ekip Dip LIG In=1600A 4p F F Circuit Breaker?

The ABB 1SDA101281R1, designated XT7L 1600 Ekip Dip LIG In=1600A 4p F F, is a high-performance four-pole moulded-case circuit breaker (MCCB) designed for reliable protection and switching in demanding low-voltage electrical distribution systems. As part of the ABB SACE Tmax XT7 range, it combines a 1600 A rated uninterrupted current with an Ekip Dip LIG electronic trip unit and the high short-circuit performance of the XT7L platform.

The circuit breaker incorporates an Ekip Dip LIG electronic trip unit, providing long-time overload, instantaneous short-circuit and ground-fault protection. The long-time protection threshold can be adjusted to suit the protected circuit, while the instantaneous protection provides rapid response to severe short-circuit conditions. This makes the XT7L suitable for transformer, generator and installation protection in demanding industrial power systems.

With a rated uninterrupted current of 1600 A and a rated ultimate short-circuit breaking capacity of 120 kA at 400 V AC, 50 Hz, the XT7L 1600 provides robust protection for high-current distribution systems. Its fixed four-pole construction with front terminals and lever operating mechanism enables straightforward integration into low-voltage switchboards and major electrical distribution assemblies.

Reliable Protection for High-Current Power Distribution

Moulded-case circuit breakers such as the ABB XT7L protect low-voltage electrical installations against damaging overcurrents and fault conditions while providing dependable circuit switching and isolation. The high short-circuit breaking performance of the XT7L platform makes it particularly suitable for industrial and infrastructure systems where prospective fault currents can be substantial.

The Ekip Dip LIG electronic trip unit combines long-time overload, instantaneous short-circuit and ground-fault protection in a configurable electronic protection system. Together with the XT7L's four-pole construction, 1600 A current rating and 120 kA breaking capacity at 400 V AC, this provides a robust solution for protecting transformers, generators, feeders and major low-voltage distribution circuits.

Typical Applications

• Industrial low-voltage switchboards and distribution panels.
• Transformer protection and secondary distribution systems.
• Generator protection and generator distribution systems.
• Main incoming and outgoing power distribution circuits.
• Manufacturing and process industry electrical installations.
• Commercial and infrastructure power distribution.
