1SDA100966R1 ABB XT7L 800 Ekip Touch LSI 800 A 3-Pole MCCB

Why Choose the ABB 1SDA100966R1 XT7L 800 Circuit Breaker?

The ABB 1SDA100966R1 is a high-performance three-pole moulded-case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage power distribution systems. Part of the ABB SACE Tmax XT7 range, this fixed circuit breaker combines an 800 A rated current with an Ekip Touch LSI electronic trip unit for precise and configurable electrical protection.

The integrated Ekip Touch LSI solid-state electronic release provides long-time overload, selective short-time and instantaneous short-circuit protection functions. Its electronic protection technology enables accurate protection settings and effective coordination with other protective devices, making the XT7L suitable for critical industrial, commercial and infrastructure distribution systems.

The XT7L version is engineered for very high short-circuit performance, providing a rated ultimate breaking capacity of 120 kA at 415 V AC. The 1SDA100966R1 features a fixed three-pole construction with front terminals and a lever operating mechanism, providing a robust solution for switchboards and distribution assemblies where substantial prospective fault currents may be present.
