1SDA073124R1 ABB E4.2N 3200 Ekip Touch LI 4p WMP Air Circuit Breaker 3200 A

Why Choose the ABB E4.2N 3200 Ekip Touch LI 4p WMP Air Circuit Breaker?

The ABB E4.2N 3200 Ekip Touch LI 4p WMP, order code 1SDA073124R1, is a high-current four-pole air circuit breaker moving part from the ABB SACE Emax 2 range. Rated at 3200 A, it is designed for protection and switching in demanding low-voltage industrial, commercial, infrastructure and critical-power distribution systems.

This E4.2N breaker is equipped with an advanced Ekip Touch LI electronic trip unit, providing long-time overload (L) and instantaneous short-circuit (I) protection. The Ekip Touch platform combines accurate electronic protection with an intuitive touchscreen interface, making protection configuration and access to operating information straightforward.

The N performance level provides a rated ultimate short-circuit breaking capacity of 66 kA at 400 V AC. Its WMP configuration is the moving part of a withdrawable Emax 2 breaker system and connects through a separate fixed chassis, supporting efficient inspection, servicing and replacement in high-current switchboards.

Advanced LI Protection for High-Current Power Distribution

The ABB E4.2N 3200 uses the Ekip Touch LI electronic release to protect high-current electrical distribution circuits against sustained overloads and severe short circuits. The long-time function provides adjustable overload protection, while the instantaneous function rapidly trips the breaker when a high-level short-circuit current is detected.

With a 3200 A current rating, 66 kA breaking capacity at 400 V AC and withdrawable construction, the E4.2N is well suited to high-current switchboards where reliable protection and maintainability are important. The moving part connects to a separately ordered fixed part, allowing the breaker to be withdrawn for inspection or servicing without disturbing the switchboard's permanent main connections.

Typical Applications

• Main incoming protection for high-current low-voltage switchboards.
• Industrial power distribution systems.
• High-current feeder and distribution protection.
• Manufacturing and process plants.
• Large commercial building electrical distribution.
• Data centres and critical infrastructure.
• Utility and infrastructure distribution systems.
• Generator and transformer distribution switchboards.
