Why Choose the ABB E1.2B 1250 Ekip Touch LSIG 4p WMP Air Circuit Breaker?
The ABB 1SDA072806R1 is a SACE Emax 2 E1.2B air circuit breaker designed for protection, switching and control in low-voltage electrical distribution systems. Rated at 1250 A, this four-pole withdrawable breaker combines ABB's compact E1.2 frame with an advanced Ekip Touch LSIG electronic trip unit, providing Long-time, Short-time, Instantaneous and Ground-fault protection.
The E1.2B performance level provides a breaking capacity of 42 kA, while the breaker is rated for systems up to 690 V AC. Its comprehensive LSIG protection makes it well suited to industrial, commercial and infrastructure distribution systems where overload protection, selective short-circuit coordination and earth-fault protection are required from a single electronic release.
This model is supplied as a four-pole withdrawable moving part (WMP) for use with the appropriate Emax 2 fixed part. ABB specifies the breaker with an Ekip Touch LSIG R 1250 solid-state release, four auxiliary contacts and circuit-breaker open/closed position indication, supporting effective integration into modern switchboards, signalling circuits and power-management systems.

Comprehensive LSIG Protection for Power Distribution
The ABB SACE Emax 2 E1.2B provides a robust switching and protection point within low-voltage power-distribution systems. Its Ekip Touch LSIG release combines Long-time overload protection, Short-time selective short-circuit protection, Instantaneous short-circuit protection and Ground-fault protection. This combination enables comprehensive electronic protection against the principal overcurrent and earth-fault conditions encountered in industrial and commercial electrical networks.
With a 1250 A current rating, 42 kA breaking capacity and advanced Ekip Touch protection, the E1.2B is suited to demanding distribution boards and switchboards. Its withdrawable construction allows the moving breaker portion to be separated from the appropriate fixed part, supporting efficient inspection, servicing and replacement where maintainability and system availability are important.
Typical Applications
- Main and distribution switchboards.
- Industrial low-voltage power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process-control facilities.
- Data centres and critical-power distribution.
- Infrastructure and utility installations.
- Transformer secondary and generator distribution.
- Four-pole circuits requiring comprehensive LSIG electronic protection and selective coordination.
