1SDA100319R1 ABB Ekip Touch LSI 160 A XT4 4-Pole Trip Unit

Why Choose the ABB 1SDA100319R1 Ekip Touch LSI 160 A XT4 4-Pole Trip Unit?

The ABB 1SDA100319R1 is an advanced Ekip Touch LSI electronic trip unit designed for compatible SACE Tmax XT4 moulded-case circuit breakers. Rated at 160 A and configured for 4-pole applications, it combines microprocessor-based protection with ABB's intuitive Ekip Touch interface for modern low-voltage power distribution.

The Ekip Touch LSI release provides long-time (L), short-time (S) and instantaneous (I) protection, covering overload and short-circuit conditions while supporting selective coordination within electrical distribution systems. The protection is adjustable for overload from 0.4–1 × In and for short-circuit conditions from 1–10 × In, with time-delay capability supporting coordinated protection strategies.

The 1SDA100319R1 is specifically designed for XT4 4-pole circuit-breaker configurations and has a rated current of 160 A. It is a separate electronic protection release rather than a complete moulded-case circuit breaker and must be combined with an appropriate compatible XT4 breaking part to create the required circuit-breaker assembly.

Advanced LSI Protection for SACE Tmax XT4

The ABB Ekip Touch LSI platform combines three complementary electronic protection functions. Long-time protection responds to sustained overload conditions, short-time protection provides configurable short-circuit protection with time-delay capability for improved selectivity, and instantaneous protection enables rapid interruption when severe short-circuit conditions occur.

For the 160 A 1SDA100319R1, overload protection is adjustable from 0.4–1 × In, corresponding to approximately 64–160 A. As a separate four-pole electronic release, it can be combined with an appropriate SACE Tmax XT4 breaking part to create a circuit breaker with the required interruption capability while retaining the configurable protection and upgrade potential of the Ekip Touch platform.

Typical Applications

• ABB SACE Tmax XT4 circuit-breaker assemblies.
• Industrial low-voltage power distribution.
• Commercial building electrical distribution.
• Main and sub-distribution switchboards.
• Manufacturing and process facilities.
• Four-pole feeder and cable protection.
• Systems requiring selective electronic short-circuit protection.
• Applications requiring configurable overload and short-circuit protection.
