1SDA073347R1 ABB E6.2V/f 5000 Ekip G Touch LSIG 4p WMP Air Circuit Breaker

Why Choose the ABB E6.2V/f 5000 Ekip G Touch LSIG 4p WMP Air Circuit Breaker?

The ABB E6.2V/f 5000 Ekip G Touch LSIG 4p WMP, order code 1SDA073347R1, is a high-performance SACE Emax 2 withdrawable air circuit breaker moving part designed for generator protection and demanding high-current low-voltage power-distribution systems. Part of the ABB Emax 2 E6.2 full-size range, this four-pole breaker combines a 5000 A rated uninterrupted current, V-level short-circuit performance and an advanced Ekip G Touch LSIG electronic protection release.

The integrated Ekip G Touch LSIG trip unit provides long-time overload (L), selective short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. The generator-oriented Ekip G Touch platform extends these core current-protection functions with advanced protection, measurement and supervision capabilities for generators and complex electrical networks, while its touchscreen interface provides convenient configuration and access to operating information.

The E6.2V/f 5000 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. The withdrawable moving part is designed for use with the corresponding Emax 2 fixed part, supporting efficient isolation, inspection and servicing in critical switchboards.

Advanced Generator and High-Current Distribution Protection

Air circuit breakers used in generator and major distribution systems must provide dependable protection against overloads, short circuits and earth faults while supporting selective coordination across the electrical network. The Ekip G Touch LSIG release combines L, S, I and G current-protection functions with generator-oriented protection and supervision capabilities, making the 1SDA073347R1 particularly suitable for sophisticated generation and distribution architectures.

The combination of a 5000 A continuous-current rating, 150 kA breaking capacity at 400/415/440 V AC and 100 kA short-time withstand capability enables the E6.2V/f to operate in switchboards with substantial prospective fault levels. Its withdrawable architecture also allows the breaker moving part to be isolated from the separately installed fixed section, supporting inspection, servicing and continuity strategies in critical electrical installations.

Typical Applications

• Generator protection in low-voltage power-generation systems.
• Main incoming protection in high-current low-voltage switchboards.
• Industrial power-generation and cogeneration installations.
