1SDA073253R1 ABB E6.2V 5000 Ekip Dip LSIG 4p WMP Air Circuit Breaker

Why Choose the ABB E6.2V 5000 Ekip Dip LSIG 4p WMP Air Circuit Breaker?

The ABB E6.2V 5000 Ekip Dip LSIG 4p WMP, order code 1SDA073253R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for protection and switching in demanding high-current low-voltage power-distribution systems. Part of the ABB Emax 2 E6.2 series, this withdrawable four-pole breaker combines a 5000 A rated current, V-level breaking performance and an Ekip Dip LSIG electronic protection release.

The integrated Ekip Dip LSIG trip unit provides long-time overload (L), selective short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. Its adjustable electronic protection functions enable the breaker to protect major distribution circuits while supporting selective coordination between upstream and downstream protective devices.

The E6.2V 5000 delivers an ultimate short-circuit breaking capacity of 150 kA at 400/415 V AC and 100 kA at 690 V AC. The withdrawable moving-part configuration interfaces with the corresponding Emax 2 fixed part, while four changeover auxiliary contacts provide circuit-breaker open/closed status signalling for switchboard control and monitoring systems.

Reliable LSIG Protection for High-Current Distribution

Air circuit breakers such as the ABB Emax 2 E6.2V provide switching and protection for major low-voltage distribution circuits where high continuous currents and substantial prospective fault currents must be managed safely. The Ekip Dip LSIG release monitors circuit current and provides separate long-time, short-time, instantaneous and earth-fault protection functions, enabling comprehensive protection of conductors, busbars and connected electrical equipment.

The combination of 5000 A continuous current capability, selective LSIG protection and high short-circuit breaking performance makes the 1SDA073253R1 particularly suitable for large switchboards and critical distribution systems. Its withdrawable architecture also allows the breaker moving part to be isolated from the fixed section for inspection or servicing, supporting maintainability and continuity strategies in industrial power systems.

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 LSIG and earth-fault protection.
