Why Choose the ABB Ekip LSI In=40A XT4 3P Trip Unit?
The ABB 1SDA067508R1 is an Ekip LSI electronic trip unit designed for three-pole ABB SACE Tmax XT4 moulded-case circuit-breakers used in power distribution applications. Identified by ABB as Ekip LSI In=40A XT4 3P, it provides electronic long-time, short-time and instantaneous overcurrent protection in a compact release designed specifically for the Tmax XT4 platform.
As part of the ABB Tmax XT electronic protection range, the Ekip LSI combines L, S and I protection functions. Long-time protection responds to sustained overloads, short-time protection provides selective protection against higher fault currents with time-delay capability, and instantaneous protection provides rapid operation during severe short-circuit conditions.
With a rated current of 40 A and a three-pole AC configuration, the 1SDA067508R1 offers adjustable electronic protection for compatible ABB Tmax XT4 circuit-breakers. Its overload setting can be adjusted across 0.4–1 × In, while short-circuit protection provides an adjustment range extending to 10 × In, allowing the protection characteristics to be coordinated with downstream circuits and electrical loads.

Advanced Electronic Protection for Power Distribution
Electronic LSI protection provides greater flexibility than conventional fixed protection by separating overload, short-time and instantaneous fault functions. The long-time function protects against sustained overcurrents, while the short-time function can support selective coordination between protective devices and the instantaneous function responds rapidly to severe short-circuit faults.
The ABB Ekip LSI release is designed for power distribution applications requiring adjustable protection characteristics. When combined with a compatible ABB Tmax XT4 circuit-breaker, the 40 A release provides configurable electronic protection for feeders, distribution circuits, machinery supplies and other low-voltage electrical installations.
Typical Applications
- Industrial low-voltage distribution boards.
- Commercial electrical distribution systems.
- Three-phase feeder protection.
- Industrial switchboards and control panels.
- Machine and equipment power distribution.
- Applications requiring selective short-circuit protection.
