1SDA073335R1 ABB E6.2H/f 5000 Ekip Touch LSI 4p WMP Air Circuit Breaker

Why Choose the ABB E6.2H/f 5000 Ekip Touch LSI 4p WMP Air Circuit Breaker?

The ABB E6.2H/f 5000 Ekip Touch LSI 4p WMP, order code 1SDA073335R1, is a high-performance four-pole withdrawable air circuit breaker moving part from the ABB SACE Emax 2 range. Designed for demanding high-current low-voltage distribution systems, it combines a rated current of 5000 A with an advanced Ekip Touch LSI electronic trip unit for long-time overload, short-time selective short-circuit and instantaneous short-circuit protection.

The E6.2H/f full-size platform is engineered for major switchboards where high current capacity, fault-clearing performance and protection selectivity are essential. Its Ekip Touch release provides a colour touchscreen interface for intuitive configuration and access to operating information, while optional communication capabilities allow integration into modern power-management and automation architectures.

With a rated operational voltage of 690 V AC, rated insulation voltage of 1000 V AC and rated impulse withstand voltage of 12 kV, the breaker is designed for robust industrial service. The H performance level provides a rated ultimate and service short-circuit breaking capacity of 100 kA across key operating voltages, together with a rated short-time withstand current of 100 kA for 1 s and 3 s.

Advanced Selective Protection for High-Current Distribution

Air circuit breakers such as the ABB Emax 2 E6.2H/f provide switching, isolation and protection for major low-voltage electrical distribution systems. The combination of a 5000 A current rating, 100 kA short-circuit breaking capacity and 100 kA short-time withstand capability makes this breaker well suited to main incomers, transformer secondary circuits, bus couplers and major feeders in high-power switchboards.

The Ekip Touch LSI trip unit adds adjustable short-time protection to long-time overload and instantaneous short-circuit protection, supporting selective coordination with downstream protective devices. Its touchscreen interface provides convenient access to protection parameters and operating information, while the withdrawable Emax 2 architecture supports maintainability in critical installations where continuity of service is important.
