1SDA073282R1 ABB E6.2V 6300 Ekip Dip LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E6.2V 6300 Ekip Dip LSI 4p WMP Air Circuit Breaker?

The ABB E6.2V 6300 Ekip Dip LSI 4p WMP, order code 1SDA073282R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for protection and switching of very high-current low-voltage electrical distribution systems. Part of the ABB Emax 2 E6.2V series, this four-pole breaker combines a 6300 A rated uninterrupted current with an Ekip Dip LSI solid-state electronic protection release.

The integrated Ekip Dip LSI trip unit provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. This LSI configuration supports selective protection of major distribution circuits while providing rapid interruption of severe fault currents, making it suitable for demanding industrial, infrastructure and power-distribution installations.

The E6.2V 6300 is engineered for systems with high prospective fault currents and provides a rated ultimate short-circuit breaking capacity of 150 kA at key low-voltage operating levels. Its four-pole withdrawable moving-part construction connects through the corresponding Emax 2 fixed chassis, allowing efficient inspection, servicing and replacement within high-current switchgear assemblies.

Selective LSI Protection for Very High-Current Distribution

Air circuit breakers such as the ABB Emax 2 E6.2V provide switching and protection for major low-voltage distribution circuits. By detecting overload and short-circuit conditions and interrupting the affected circuit, the breaker helps protect switchgear, conductors, transformers and other connected electrical equipment against damaging fault currents.

The Ekip Dip LSI solid-state trip unit combines long-time overload protection with short-time delayed and instantaneous short-circuit protection. Together with the 6300 A E6.2V breaker frame, high breaking capacity and withdrawable architecture, it provides a robust solution for major industrial switchboards and infrastructure systems requiring high current capacity, selective protection and maintainable switchgear construction.

Typical Applications

• Main incoming protection in very high-current low-voltage switchboards.
• Industrial power-distribution systems.
• Transformer secondary and main distribution protection.
• Generator and power-plant distribution systems.
• Large infrastructure and commercial electrical installations.
• High-fault-level switchgear and power distribution assemblies.
