1SDA073341R1 ABB E6.2V/f 5000 Ekip Dip LI 4p WMP Air Circuit Breaker

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

The ABB E6.2V/f 5000 Ekip Dip LI 4p WMP, order code 1SDA073341R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for switching and protection of very high-current low-voltage electrical distribution systems. Part of the ABB Emax 2 E6.2V/f range, this four-pole breaker combines a 5000 A rated current with the Ekip Dip LI electronic protection release.

The integrated Ekip Dip LI trip unit provides long-time overload and instantaneous short-circuit protection. This focused LI protection configuration delivers dependable electronic protection for major distribution circuits where overload protection and rapid interruption of severe short-circuit currents are required.

The E6.2V/f 5000 combines the high breaking performance of the V frame with a four-pole full-size configuration, providing a rated ultimate short-circuit breaking capacity of 150 kA at 415 V AC and 100 kA at 690 V AC. Its withdrawable moving-part construction is designed for use with the corresponding Emax 2 fixed part, supporting efficient servicing and replacement within high-current switchgear assemblies.

High-Performance LI Protection for Very High-Current Distribution

Air circuit breakers such as the ABB Emax 2 E6.2V/f provide switching and protection for major low-voltage distribution circuits. By detecting sustained overloads and severe 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 LI electronic trip unit combines long-time overload protection with instantaneous short-circuit protection in a straightforward electronic protection package. Together with the 5000 A E6.2V/f breaker architecture, breaking capacities of up to 150 kA and withdrawable construction, it provides a robust solution for industrial switchboards and infrastructure systems requiring very high current capacity and maintainable switchgear.

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 commercial and critical infrastructure installations.
• High-fault-level switchgear and power distribution assemblies.
