1SDA073276R1 ABB E6.2H 6300 Ekip Touch LSIG 4p WMP Air Circuit Breaker

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

The ABB E6.2H 6300 Ekip Touch LSIG 4p WMP, order code 1SDA073276R1, is a high-current SACE Emax 2 air circuit breaker moving part designed for protection, switching and isolation in demanding low-voltage power-distribution systems. Part of the advanced ABB Emax 2 E6.2 series, this withdrawable four-pole breaker combines a 6300 A rated continuous current with H-level breaking performance and an intelligent Ekip Touch LSIG electronic protection release.

The integrated Ekip Touch LSIG trip unit provides long-time overload (L), selective short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. Protection settings are configured through the touch-sensitive display, with adjustable functions that allow the breaker to be coordinated with the requirements of high-current distribution circuits and other protective devices in the installation.

The E6.2H 6300 is rated for operation up to 690 V AC and provides an ultimate short-circuit breaking capacity of 100 kA throughout the 380–690 V AC range. Its withdrawable moving-part configuration interfaces with the corresponding Emax 2 fixed part, supporting efficient isolation and maintenance while four auxiliary contacts provide circuit-breaker open/closed status signalling.

Reliable LSIG Protection for High-Current Distribution

Air circuit breakers such as the ABB Emax 2 E6.2H protect major low-voltage distribution circuits against overloads, short circuits and earth faults. The Ekip Touch LSIG release continuously monitors circuit conditions and provides separate long-time, short-time, instantaneous and earth-fault protection functions, enabling comprehensive protection and selective coordination throughout the electrical distribution system.

The combination of a 6300 A current rating, 100 kA breaking capability, advanced electronic protection and withdrawable architecture makes the 1SDA073276R1 particularly suitable for large industrial and infrastructure switchboards. Its Ekip Touch interface simplifies protection configuration, while the withdrawable design supports inspection and servicing without permanently disturbing the switchboard's fixed main connections.

Typical Applications

• Main incoming protection in 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 selective LSIG and earth-fault protection.
