1SDA073349R1 ABB E6.2V/f 5000 Ekip Hi-Touch LSIG 4p WMP Air Circuit Breaker

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

The ABB E6.2V/f 5000 Ekip Hi-Touch LSIG 4p WMP, order code 1SDA073349R1, is a high-performance Emax 2 air circuit breaker (ACB) designed for protection, monitoring 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 5000 A rated uninterrupted current with the sophisticated Ekip Hi-Touch LSIG electronic trip unit for comprehensive protection of critical power networks.

Designed for demanding industrial, commercial and infrastructure applications, the E6.2V/f provides very high fault-current interruption capability together with advanced electronic protection and measurement functionality. The Ekip Hi-Touch LSIG trip unit provides long-time overload (L), selective short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection, while its touchscreen interface supports convenient configuration, monitoring and management of the electrical installation.

With a rated current of 5000 A, a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 150 kA at 400 V AC, the E6.2V/f 5000 is engineered for high-capacity switchboards and critical power distribution systems with very high prospective fault currents. This WMP version is supplied as the withdrawable moving part for integration with a compatible ABB Emax 2 fixed part.

Advanced Protection for High-Current Power Distribution

Air circuit breakers such as the ABB Emax 2 E6.2 are designed to protect high-current low-voltage electrical networks against overloads, short circuits and earth faults. The E6.2V/f combines very high breaking performance with sophisticated electronic protection, making it particularly suitable for main incomers, bus couplers and high-current feeder circuits in large switchboards where severe prospective fault currents may be present.

The Ekip Hi-Touch LSIG trip unit provides long-time overload protection (L), selective short-circuit protection (S), instantaneous short-circuit protection (I) and earth-fault protection (G). Its advanced touchscreen interface and monitoring capabilities provide greater visibility and control of electrical system performance, while the selective protection functions support effective coordination between upstream and downstream protective devices.

Typical Applications

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