1SDA073371R1 ABB E6.2V/f 6300 Ekip Dip LI 4p WMP Air Circuit Breaker

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

The ABB E6.2V/f 6300 Ekip Dip LI 4p WMP, order code 1SDA073371R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for protection and control of high-current low-voltage electrical distribution systems. This four-pole E6.2 breaker combines a 6300 A rated uninterrupted current with ABB's Ekip Dip LI electronic release, providing dependable overload and instantaneous short-circuit protection for demanding power distribution applications.

The Ekip Dip LI electronic trip unit provides long-time overload (L) and instantaneous short-circuit (I) protection. Its straightforward electronic protection architecture makes the breaker well suited to installations requiring reliable high-current circuit protection without the additional selective short-circuit or earth-fault functions associated with LSI and LSIG releases.

The E6.2V/f 6300 delivers an ultimate short-circuit breaking capacity of 150 kA at 400–440 V AC, 130 kA at 500–525 V AC and 100 kA at 690 V AC. Supplied as a withdrawable moving part (WMP), it features a four-pole full-size neutral configuration and is designed for installation with a compatible ABB Emax 2 fixed part.

High-Capacity Protection for Low-Voltage Power Distribution

Air circuit breakers are used at critical points in low-voltage distribution systems where very high continuous currents and prospective short-circuit currents must be controlled safely. The ABB E6.2V/f 6300 combines a 6300 A current rating with breaking capacity reaching 150 kA, making it particularly suitable for major incomers, transformer secondary circuits, busbar systems and other high-capacity distribution duties.

The Ekip Dip LI release provides long-time overload and instantaneous short-circuit protection, helping protect conductors, switchgear and connected equipment against sustained overcurrents and severe short-circuit faults. Its withdrawable design also allows the breaker moving part to be isolated and removed from its compatible fixed part, supporting maintenance strategies for large industrial and infrastructure switchboards.

Typical Applications

• Main incomers for high-capacity low-voltage switchboards.
• Transformer secondary protection and distribution.
• High-current industrial power distribution systems.
• Manufacturing and process plant electrical infrastructure.
• Large commercial and infrastructure electrical systems.
• High-current feeders and busbar distribution systems.
