1SDA107538R1 ABB Ekip LCD LSIG E1.2..E6.2 Ed.2 Electronic Trip Unit

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

The ABB Ekip LCD LSIG E1.2..E6.2 Ed.2, order code 1SDA107538R1, is an electronic LSIG 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 interface with comprehensive electronic overcurrent and earth-fault protection.

The Ekip LCD LSIG provides long-time (L), short-time (S), instantaneous (I) and earth-fault (G) protection functions. This combination enables compatible Emax 2 circuit breakers to protect electrical installations against sustained overloads, short circuits and earth faults while supporting coordinated protection throughout low-voltage power distribution systems.

ABB specifies the 1SDA107538R1 as an Ekip LCD LSIG black-platform spare unit for Emax 2 E1.2 through E6.2 circuit breakers in compatible IEC and UL configurations. The trip unit is supplied without a Measurement Enabler or Measurement Enabler with voltage sockets and provides a common electronic protection platform across multiple Emax 2 frame sizes.

Reliable Electronic Protection for Emax 2 Circuit Breakers

Electronic trip units continuously evaluate electrical current conditions and command the associated circuit breaker to open when configured protection thresholds are exceeded. The ABB Ekip LCD LSIG combines long-time overload protection with short-time and instantaneous short-circuit protection plus earth-fault protection, providing comprehensive protection for cables, busbars, transformers and other distribution equipment.

Compatibility across the Emax 2 E1.2, E2.2, E4.2 and E6.2 frame range makes the 1SDA107538R1 a versatile protection and replacement component for compatible ABB installations. Its LSIG functionality is particularly suitable where earth-fault protection is required in addition to conventional overload and short-circuit protection.

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.
• Electrical systems requiring integrated earth-fault protection.
• Replacement and maintenance of compatible Emax 2 trip units.
