1SDA073374R1 ABB E6.2V/f 6300 Ekip Touch LI 4p WMP Air Circuit Breaker

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

The ABB E6.2V/f 6300 Ekip Touch LI 4p WMP, order code 1SDA073374R1, is a high-current SACE Emax 2 withdrawable air circuit breaker moving part engineered for protection and switching in demanding low-voltage power-distribution systems. Part of the ABB Emax 2 E6.2 full-size range, this four-pole breaker combines a 6300 A rated uninterrupted current, V-level short-circuit performance and an Ekip Touch LI electronic protection release.

The integrated Ekip Touch LI trip unit provides long-time overload (L) and instantaneous short-circuit (I) protection. Its touchscreen-based interface supports convenient protection configuration and access to operating information, making the breaker well suited to high-current installations requiring straightforward overload and instantaneous fault protection together with the capabilities of ABB's Ekip Touch platform.

The E6.2V/f 6300 delivers an 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. It also provides a rated short-time withstand current of 100 kA for both 1 s and 3 s. Its withdrawable moving-part construction is designed for use with the corresponding Emax 2 fixed part, supporting efficient isolation, inspection and maintenance in critical high-current switchboards.

High-Current Protection with Ekip Touch Control

Air circuit breakers such as the ABB Emax 2 E6.2V/f protect major low-voltage distribution circuits against overload and severe short-circuit conditions. The Ekip Touch LI release combines long-time overload protection with instantaneous short-circuit protection, providing a straightforward protection arrangement for high-current circuits where selective short-time or integrated earth-fault functions are not required.

The combination of a 6300 A continuous-current rating, 150 kA breaking capacity at 400/415/440 V AC and 100 kA short-time withstand capability makes the 1SDA073374R1 suitable for major switchboards with substantial prospective fault currents. Its withdrawable architecture allows the moving breaker assembly to be isolated from the separately installed fixed part, supporting inspection, servicing and maintainability in critical electrical installations.

Typical Applications

• Main incoming protection in very 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 long-time overload and instantaneous short-circuit protection.
