1SDA073273R1 ABB E6.2H 6300 Ekip Dip LSIG 4p WMP Air Circuit Breaker

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

The ABB E6.2H 6300 Ekip Dip LSIG 4p WMP, order code 1SDA073273R1, 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 Dip LSIG electronic trip unit for comprehensive protection of industrial and commercial power networks.

Designed for demanding power distribution applications, the E6.2H provides protection against overloads, selective short circuits, instantaneous short circuits and earth faults. The integrated Ekip Dip LSIG electronic trip unit provides adjustable protection settings using DIP switches, allowing the breaker to be configured for the requirements of the electrical installation.

With a rated current of 6300 A, a rated operational voltage of up to 690 V AC and an ultimate short-circuit breaking capacity of 100 kA at key low-voltage operating voltages, the E6.2H 6300 is engineered for high-capacity switchboards and critical electrical distribution systems. This WMP version is supplied as the withdrawable moving part for integration into compatible ABB Emax 2 installations.

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 abnormal operating conditions and potentially damaging fault currents. Their combination of high breaking capacity and electronic protection makes them particularly suitable for main incomers, bus couplers and feeder circuits in large switchboards.

The Ekip Dip LSIG trip unit provides four fundamental protection functions: long-time overload protection (L), selective short-circuit protection (S), instantaneous short-circuit protection (I) and earth-fault protection (G). Adjustable settings allow protection characteristics to be coordinated with the wider electrical distribution system while the withdrawable Emax 2 construction supports efficient installation and maintenance.

Typical Applications

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