1SDA100821R1 ABB Ekip Dip LSIG In=1000 XT6 4-Pole Electronic Trip Unit

Why Choose the ABB Ekip Dip LSIG In=1000 XT6 4p Trip Unit 1SDA100821R1?

The ABB Ekip Dip LSIG In=1000 XT6 4p 1SDA100821R1 is a four-pole electronic protection trip unit designed for compatible ABB SACE Tmax XT6 moulded case circuit breakers. Rated at 1000 A, it provides comprehensive electronic protection for demanding low-voltage power distribution applications while supporting the modular architecture of the Tmax XT6 platform.

The Ekip Dip LSIG combines long-time overload protection (L), short-time short-circuit protection (S), instantaneous short-circuit protection (I) and earth-fault protection (G). This combination provides coordinated protection against sustained overloads, short circuits and earth faults, making it suitable for high-current industrial, commercial and infrastructure distribution systems.

Designed specifically for the ABB Tmax XT6 four-pole platform, the 1SDA100821R1 is supplied as a separate electronic protection release and must be combined with a compatible four-pole XT6 breaking part. Its four-pole configuration and LSIG functionality make it particularly suitable for distribution systems requiring comprehensive electronic protection and switching of all four poles.

Comprehensive LSIG Protection for Four-Pole Distribution Systems

The ABB Ekip Dip LSIG trip unit combines four complementary electronic protection functions. Long-time protection responds to sustained overloads, short-time protection supports selective coordination during short-circuit conditions, instantaneous protection provides rapid operation during severe faults, and ground protection detects earth-fault currents. Together, these functions provide comprehensive protection for demanding low-voltage distribution systems.

With its 1000 A rated current and four-pole configuration, the 1SDA100821R1 is suited to high-current distribution systems requiring coordinated electronic protection. When combined with a compatible four-pole ABB XT6 breaking part, it forms part of a configurable moulded case circuit breaker solution for protecting feeders, cables, switchboards and other critical electrical distribution infrastructure.
