1SDA100963R1 ABB XT7L 1000 Ekip Dip LSIG 1000 A 3P MCCB

Why Choose the ABB XT7L 1000 Ekip Dip LSIG 1SDA100963R1 Circuit Breaker?

The ABB XT7L 1000 Ekip Dip LSIG 1SDA100963R1 is a high-performance three-pole moulded case circuit breaker (MCCB) designed for dependable protection and switching of low-voltage AC power distribution systems. As part of the advanced ABB SACE Tmax XT series, this fixed circuit breaker combines a 1000 A current rating with an electronic Ekip Dip LSIG trip unit for comprehensive overload, short-circuit and earth-fault protection.

The XT7L is engineered for demanding industrial and commercial electrical installations where high breaking capacity, selective protection and reliable operation are essential. Its solid-state Ekip Dip LSIG release provides long-time, short-time, instantaneous and earth-fault protection functions, while the fixed three-pole construction, front terminals and lever operating mechanism support straightforward integration into switchboards and power distribution assemblies.

With a rated current of 1000 A and a rated ultimate short-circuit breaking capacity of 120 kA at 415 V AC, the XT7L 1000 is suitable for substantial industrial loads and distribution feeders requiring robust fault protection. Adjustable protection thresholds include long-time protection from 0.4–1 × In, short-time protection from 1–10 × In and instantaneous protection from 1–15 × In, while the LSIG configuration also provides dedicated earth-fault protection.
