1SDA107537R1 ABB Ekip LCD LSI E1.2..E6.2 Ed.2 Electronic Trip Unit

Why Choose the ABB Ekip LCD LSI E1.2..E6.2 Ed.2 Trip Unit?

The ABB Ekip LCD LSI E1.2..E6.2 Ed.2, order code 1SDA107537R1, is an electronic LSI protection trip unit for compatible ABB SACE Emax 2 air circuit breakers. Designed for the E1.2, E2.2, E4.2 and E6.2 frame sizes, this Edition 2 black-platform Ekip unit combines an LCD human-machine interface with electronic protection for demanding low-voltage power distribution applications.

The Ekip LCD LSI provides long-time (L), short-time (S) and instantaneous (I) overcurrent protection. These functions enable the compatible Emax 2 circuit breaker to protect electrical installations against sustained overloads and short-circuit faults while supporting coordinated protection across upstream and downstream distribution devices.

ABB identifies the 1SDA107537R1 as an Ekip LCD LSI black-platform unit for Emax 2 E1.2 through E6.2 circuit breakers. It is supplied as an Ekip trip-unit spare component and is suitable for both IEC and UL Emax 2 configurations, providing a common protection platform across multiple Emax 2 frame sizes.

Reliable Electronic Protection for Emax 2 Circuit Breakers

Electronic trip units continuously evaluate current conditions in the protected electrical circuit and command the associated circuit breaker to open when configured protection thresholds are exceeded. The ABB Ekip LCD LSI combines long-time protection against sustained overloads with short-time and instantaneous functions for short-circuit protection, supporting coordinated protection of cables, busbars, transformers and other distribution equipment.

Its compatibility across the Emax 2 E1.2, E2.2, E4.2 and E6.2 frame range makes the 1SDA107537R1 a versatile replacement component for compatible ABB installations. The LCD interface provides a practical local interface while the Ekip architecture allows the protection system to form part of ABB's broader Emax 2 circuit-breaker platform.

Typical Applications

• ABB SACE Emax 2 air circuit breakers.
• Industrial low-voltage distribution switchboards.
• Main incoming and feeder circuit protection.
• Commercial and infrastructure power distribution systems.
• Protection of cables, busbars and distribution equipment.
• Replacement and maintenance of compatible Emax 2 trip units.
• IEC and UL Emax 2 circuit-breaker installations.
