1SDA073312R1 ABB E6.2V/f 4000 Ekip Dip LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E6.2V/f 4000 Ekip Dip LSI 4p WMP Air Circuit Breaker?

The ABB E6.2V/f 4000 Ekip Dip LSI 4p WMP, order code 1SDA073312R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for protection and switching in demanding low-voltage power-distribution systems. Part of the ABB Emax 2 E6.2 full-size range, this withdrawable four-pole breaker combines a 4000 A rated continuous current, V-level breaking performance and an Ekip Dip LSI electronic protection release.

The integrated Ekip Dip LSI trip unit provides long-time overload (L), selective short-time short-circuit (S) and instantaneous short-circuit (I) protection. The addition of the short-time protection function enables time-selective coordination with downstream protective devices, helping isolate faults closer to their source while maintaining continuity on unaffected sections of the distribution system.

The E6.2V/f 4000 provides an ultimate short-circuit breaking capacity of 150 kA at 415 V AC and 100 kA at 690 V AC, together with a 100 kA short-time withstand current for 1 s. Its withdrawable moving-part configuration is supplied with four auxiliary contacts and a trip-signalling contact as standard, while the corresponding fixed part is ordered separately.

Reliable Selective Protection for High-Current Distribution

Air circuit breakers such as the ABB Emax 2 E6.2V/f protect major low-voltage distribution circuits against overload and short-circuit conditions. The Ekip Dip LSI release combines long-time overload protection with short-time and instantaneous short-circuit functions, allowing protection settings to be coordinated across multiple levels of an electrical distribution system.

The combination of a 4000 A continuous-current rating, 150 kA breaking capacity at 415 V AC and 100 kA short-time withstand capability makes the 1SDA073312R1 suitable for high-fault-level switchboards where selectivity and continuity are important. Its withdrawable construction also allows the breaker moving part to be isolated from the fixed section for inspection or servicing, supporting maintainability in critical installations.

Typical Applications

• Main incoming protection in high-current low-voltage switchboards.
• Industrial power-distribution systems.
• Transformer secondary protection and distribution.
• Generator and power-generation distribution systems.
• Manufacturing and process-industry switchboards.
• Commercial and infrastructure electrical distribution.
• Data centres and continuity-critical power systems.
• High-current feeders requiring selective LSI protection.
