Why Choose the ABB E1.2N/E9 1250 Ekip Hi-Touch LSIG 3p WMP?
The ABB E1.2N/E9 1250 Ekip Hi-Touch LSIG 3p WMP, order code 1SDA104297R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for demanding low-voltage AC power distribution systems. Built on the compact E1.2 frame, this three-pole withdrawable configuration combines a rated uninterrupted current of 1250 A with ABB's advanced Ekip Hi-Touch LSIG electronic protection release.
The Ekip Hi-Touch LSIG trip unit provides comprehensive electronic protection covering overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) functions. As ABB's advanced touch-based protection platform, Ekip Hi-Touch is suited to installations requiring sophisticated protection, measurement and power-system supervision.
This E1.2N/E9 version has a rated operational voltage of 800 V AC and is designed as a three-pole withdrawable moving part (WMP) for connection to a separate compatible chassis. ABB specifies rear flat horizontal terminal connections, four change-over auxiliary contacts and an IP30 degree of protection for this configuration.

Advanced Ekip Hi-Touch Protection for Emax 2
Air circuit breakers protect high-current distribution circuits against electrical faults while providing switching and isolation functions within low-voltage switchgear. The ABB Emax 2 platform combines these fundamental circuit-breaker functions with electronic protection technology, enabling protection characteristics to be configured to suit the requirements of the electrical distribution system.
The Ekip Hi-Touch LSIG release gives the 1SDA104297R1 comprehensive protection against overloads, delayed and instantaneous short circuits and earth faults. Combined with its 1250 A E1.2N/E9 power section and withdrawable construction, this makes the breaker suitable for installations requiring advanced protection together with convenient inspection, servicing and switchgear maintenance.
Typical Applications
- Main low-voltage power distribution switchboards.
- Transformer and installation protection.
- Generator and critical power distribution systems.
- Industrial manufacturing and process facilities.
- Commercial and infrastructure electrical distribution.
- Withdrawable switchgear requiring advanced LSIG protection.
