Why Choose the ABB Ekip Touch LSI XT7/XT7M 1SDA101921R1 Trip Unit?
The ABB 1SDA101921R1 is an Ekip Touch LSI electronic trip unit designed for ABB SACE Tmax XT7 and XT7M moulded case circuit breakers. Developed for distribution protection, this interchangeable electronic release provides sophisticated circuit protection through long-time, short-time and instantaneous (LSI) protection functions.
The Ekip Touch platform provides an intuitive interface for configuring and managing protection functions while supporting the advanced capabilities of the ABB SACE Tmax XT system. The 1SDA101921R1 is intended for XT7/XT7M circuit breakers and can be used with compatible three- or four-pole configurations, allowing the protection unit to form part of a flexible high-current distribution solution.
Unlike the Ekip Touch LSIG version, the Ekip Touch LSI configuration concentrates on long-time overload, short-time short-circuit and instantaneous short-circuit protection without the additional ground-fault protection function. It is therefore well suited to distribution systems where adjustable electronic LSI protection is required.

Advanced LSI Distribution Protection
The Ekip Touch LSI release provides three fundamental electronic protection functions for low-voltage distribution systems. Long-time protection responds to sustained overload conditions, short-time protection provides controlled response to high fault currents and supports system selectivity, while instantaneous protection enables rapid circuit interruption when severe short-circuit conditions occur.
The 1SDA101921R1 is supplied as a dedicated trip-unit component rather than a complete circuit breaker. It is designed for compatible ABB SACE Tmax XT7 and XT7M circuit breakers, allowing the protection release to be selected as part of a configured breaker solution. Correct compatibility, current sensor/current rating and breaker configuration should be confirmed when assembling or replacing an XT7/XT7M protection unit.
Typical Applications
- ABB SACE Tmax XT7 circuit-breaker protection.
- ABB SACE Tmax XT7M circuit-breaker protection.
- Main low-voltage distribution boards.
- Industrial switchboards and distribution assemblies.
- Incoming and outgoing feeder protection.
- Transformer secondary distribution systems.
- Manufacturing and process-industry electrical systems.
- Commercial and infrastructure power distribution requiring electronic LSI protection.

Frequently Asked Questions
What is the ABB 1SDA101921R1?
The ABB 1SDA101921R1 is an Ekip Touch LSI electronic trip unit for compatible ABB SACE Tmax XT7 and XT7M moulded case circuit breakers, designed to provide electronic distribution protection.
What protection functions does the ABB Ekip Touch LSI provide?
The Ekip Touch LSI provides long-time (L), short-time (S) and instantaneous (I) protection functions, covering overload and short-circuit protection requirements in compatible low-voltage distribution systems.
Does the ABB 1SDA101921R1 provide ground-fault protection?
The 1SDA101921R1 is the LSI version and does not provide the additional ground-fault protection function identified by the G in an LSIG release. For an XT7/XT7M Ekip Touch LSIG configuration, ABB offers a separate trip-unit version.
Which circuit breakers are compatible with the ABB 1SDA101921R1?
The 1SDA101921R1 is designed for compatible ABB SACE Tmax XT7 and XT7M circuit breakers and is listed by ABB for three- and four-pole configurations.
Is the ABB 1SDA101921R1 a complete circuit breaker?
No. The 1SDA101921R1 is an electronic protection trip unit rather than a complete moulded case circuit breaker. It is intended to be used with a compatible ABB SACE Tmax XT7 or XT7M breaker configuration.
Trusted Electronic Protection for ABB SACE Tmax XT
ABB Ekip electronic trip units provide configurable protection technology for SACE Tmax XT circuit breakers, supporting dependable overload and short-circuit protection across industrial, commercial and infrastructure low-voltage distribution systems.
