Why Choose the ABB XT7L M 1600 Ekip Dip LIG 1SDA101821R1 Circuit Breaker?
The ABB 1SDA101821R1, designated XT7L M 1600 Ekip Dip LIG In=1600A 4p F F, is a high-performance four-pole moulded case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage AC power distribution systems. Part of the ABB SACE Tmax XT7 range, it combines a 1600 A rated current with an Ekip Dip LIG electronic trip unit and the high short-circuit interruption capability of the XT7L platform.
The ABB Ekip Dip LIG electronic trip unit provides long-time overload (L), instantaneous short-circuit (I) and ground-fault (G) protection. This combination provides dependable protection against sustained overloads, severe short-circuit faults and earth faults, making the breaker suitable for high-current distribution systems where integrated ground-fault protection is required without a short-time protection function.
With a 1600 A current rating, four-pole construction and front terminal configuration, the 1SDA101821R1 is engineered for integration into high-capacity switchboards and power distribution assemblies. The XT7L platform provides 120 kA short-circuit interruption performance, making it particularly suitable for installations with very high prospective fault currents.
