1SDA073376R1 ABB E6.2V/f 6300 Ekip Touch LSIG 4p WMP Air Circuit Breaker

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

The ABB E6.2V/f 6300 Ekip Touch LSIG 4p WMP, order code 1SDA073376R1, 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 full-size-neutral breaker combines a 6300 A rated uninterrupted current with the advanced Ekip Touch LSIG solid-state electronic protection release.

The integrated Ekip Touch LSIG trip unit provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection. This comprehensive LSIG configuration supports selective coordination while adding dedicated ground-fault protection, with the Ekip Touch platform providing an intuitive interface for protection configuration and access to operating information.

The E6.2V/f 6300 is rated at 690 V AC and provides a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC. Its four-pole full-size-neutral withdrawable moving-part construction connects through a separate chassis part, supporting efficient inspection, servicing and replacement within compatible high-current Emax 2 switchgear assemblies.

Comprehensive LSIG Protection for 6300 A Power 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, short-circuit conditions and earth faults and interrupting the affected circuit, the breaker helps protect switchgear, conductors, transformers and other connected electrical equipment against potentially damaging fault currents.

The Ekip Touch LSIG electronic trip unit combines long-time overload protection with short-time delayed, instantaneous and earth-fault protection. Together with the 6300 A E6.2V/f breaker architecture, 150 kA breaking capacity at 400 V AC and withdrawable construction, it provides a robust solution for industrial switchboards and infrastructure systems requiring very high current capacity, comprehensive electronic protection 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.
