1SDA100328R1 ABB Ekip Touch Measuring LSIG 160 A XT4 4-Pole Trip Unit

Why Choose the ABB 1SDA100328R1 Ekip Touch Measuring LSIG Trip Unit?

The ABB 1SDA100328R1 is an Ekip Touch Measuring LSIG electronic trip unit designed for compatible ABB Tmax XT4 4-pole moulded case circuit breakers. Rated at 160 A, it combines configurable electronic circuit protection with integrated measurement capabilities for modern AC low-voltage power distribution systems.

Its LSIG protection functions provide long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. The Measuring version extends the Ekip Touch platform with electrical measurement functionality, making it particularly suitable for installations where circuit protection and energy-management data are required from the same circuit-breaker platform.

The 1SDA100328R1 is a 4-pole protection release intended to be combined with a compatible ABB Tmax XT4 breaking part rather than used as a complete circuit breaker on its own. ABB application documentation pairs this trip unit with XT4 breaking parts and compatible Ekip communication modules, supporting connected distribution systems and integration with energy-management architectures.

Protection, Measurement and Connected Distribution

ABB Ekip Touch Measuring combines configurable electronic circuit protection with integrated electrical measurement capabilities. This allows the circuit-breaker platform to contribute operational data as well as protection, helping engineers monitor electrical distribution systems and supporting more informed energy-management and maintenance strategies.

With LSIG functionality, the 1SDA100328R1 protects against sustained overloads, time-coordinated short circuits, severe instantaneous faults and ground or earth faults. ABB also specifies this trip unit within connected distribution architectures alongside compatible Ekip communication modules, allowing the Tmax XT platform to form part of wider monitoring and energy-management systems.
