1SDA073274R1 ABB E6.2H 6300 Ekip Touch LI 4p WMP Air Circuit Breaker

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

The ABB E6.2H 6300 Ekip Touch LI 4p WMP, order code 1SDA073274R1, is a high-performance Emax 2 air circuit breaker (ACB) designed for protection and control of high-current low-voltage electrical distribution systems. As part of the advanced ABB Emax 2 series, this four-pole circuit breaker combines a 6300 A rated current with the Ekip Touch LI electronic trip unit for dependable overload and instantaneous short-circuit protection.

Designed for demanding industrial and commercial power distribution applications, the E6.2H provides a high breaking capacity together with advanced electronic protection. The Ekip Touch LI trip unit provides long-time overload (L) and instantaneous short-circuit (I) protection, with an intuitive touchscreen interface for monitoring, configuration and protection management.

With a rated current of 6300 A, a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 100 kA at 400 V AC, the E6.2H 6300 is engineered for high-capacity switchboards and critical power distribution systems. This WMP version is a withdrawable moving part, allowing integration with the appropriate ABB Emax 2 fixed part.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB Emax 2 E6.2 are used to protect high-current low-voltage electrical networks against overloads and potentially damaging short-circuit currents. Their combination of high breaking capacity, electronic protection and withdrawable construction makes them particularly suitable for main incomers, bus couplers and high-current feeder circuits in large electrical switchboards.

The Ekip Touch LI trip unit provides two fundamental protection functions: long-time overload protection (L) and instantaneous short-circuit protection (I). Its touchscreen interface provides an accessible platform for protection configuration and electrical system monitoring, while the withdrawable Emax 2 construction supports efficient inspection, servicing and replacement within compatible switchgear assemblies.

Typical Applications

• Main incomers for low-voltage switchboards.
• High-current industrial power distribution systems.
• Manufacturing and process plant electrical distribution.
• Commercial and infrastructure power systems.
• Transformer secondary protection and distribution.
• Bus coupler and high-current feeder applications.
