1SDA072696R1 ABB E1.2C 630 Ekip Touch LSIG 4P WMP Air Circuit Breaker

Why Choose the ABB E1.2C 630 Ekip Touch LSIG 4p WMP Air Circuit Breaker?

The ABB 1SDA072696R1 is a high-performance SACE Emax 2 E1.2C air circuit breaker designed for protection, switching and control in low-voltage electrical distribution systems. Rated at 630 A, this four-pole withdrawable breaker combines ABB's compact E1.2 frame with the advanced Ekip Touch LSIG electronic trip unit, providing comprehensive protection against overload, short-circuit and earth-fault conditions.

As part of the ABB SACE Emax 2 range, the E1.2C 630 combines compact switchboard integration with strong electrical performance. The C performance level provides a rated ultimate short-circuit breaking capacity of 50 kA at 400 V AC, while its 690 V AC rated voltage makes it suitable for a wide range of industrial, commercial and infrastructure power-distribution systems.

This model is supplied as a four-pole withdrawable moving part (WMP) for connection through the appropriate separate chassis or fixed part. Its Ekip Touch LSIG release provides Long-time, Short-time, Instantaneous and Ground-fault protection, while the touchscreen-based Ekip platform supports intuitive configuration and monitoring of the circuit breaker's protection functions.

Comprehensive LSIG Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E1.2 protect low-voltage distribution circuits against damaging electrical faults while providing a robust switching point within the power system. The Ekip Touch LSIG release combines Long-time overload, Short-time delayed, Instantaneous and Ground-fault protection, allowing the breaker to respond appropriately to different fault conditions and supporting selective coordination throughout a distribution network.

The E1.2C platform combines a compact Emax 2 frame with a 630 A current rating and 50 kA breaking capacity at 400 V AC. Its withdrawable construction allows the moving breaker portion to be separated from the corresponding fixed chassis, supporting efficient inspection, maintenance and replacement in industrial, commercial and infrastructure switchboard installations.

Typical Applications

• Main and distribution switchboards.
• Industrial low-voltage power distribution systems.
• Commercial building electrical distribution.
• Manufacturing and process-control facilities.
• Infrastructure and utility installations.
• Transformer secondary distribution.
• Generator and auxiliary power distribution systems.
• Four-pole circuits requiring integrated earth-fault protection.
