1SDA073283R1 ABB E6.2V 6300 Ekip Dip LSIG 4p WMP Air Circuit Breaker 6300 A

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

The ABB E6.2V 6300 Ekip Dip LSIG 4p WMP, order code 1SDA073283R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection and switching in very high-current low-voltage power distribution systems. With a rated uninterrupted current of 6300 A, it combines the large E6.2 frame and V performance level with an Ekip Dip LSIG electronic protection release.

The Ekip Dip LSIG release provides adjustable long-time overload, short-time selective short-circuit, instantaneous short-circuit and ground-fault protection. Protection thresholds are configured using DIP switches, providing straightforward adjustment while supporting selective coordination and comprehensive fault protection in demanding electrical distribution networks.

The E6.2V performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 400/415/440 V AC, 130 kA at 500/525 V AC and 100 kA at 690 V AC. This four-pole model is supplied as a withdrawable moving part, supporting efficient isolation, inspection and maintenance within compatible ABB SACE Emax 2 switchgear assemblies.

Comprehensive Protection for Very High-Current Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 provide switching, isolation and protection for high-current low-voltage electrical installations. The E6.2 platform is engineered for major power distribution systems, combining a very high continuous current rating with exceptional short-circuit breaking performance for main switchboards, industrial plants, infrastructure and other critical electrical networks.

The Ekip Dip LSIG electronic trip unit combines adjustable long-time, short-time and instantaneous overcurrent protection with ground-fault protection. Together with the breaker’s 6300 A current rating, 150 kA breaking capacity at 400/415/440 V AC and withdrawable construction, this makes the E6.2V suitable for high-power installations requiring comprehensive fault protection, selective coordination and maintainability.

Typical Applications

• Very high-current low-voltage main distribution switchboards.
• Heavy industrial power distribution systems.
• Power generation and utility distribution installations.
• Data centres and critical infrastructure.
• Large commercial and infrastructure electrical systems.
• Transformer secondary and high-current distribution applications.
• Incoming and outgoing switchgear feeders requiring comprehensive LSIG protection.
