1SDA072616R1 ABB E6.2H 5000 Ekip Touch LSIG 3P WMP Air Circuit Breaker

Why Choose the ABB 1SDA072616R1 E6.2H 5000 Ekip Touch LSIG Air Circuit Breaker?

The ABB 1SDA072616R1 is a high-current SACE Emax 2 E6.2H 5000 air circuit breaker moving part designed for comprehensive protection and switching in demanding low-voltage AC power distribution systems. Configured as an E6.2H 5000 Ekip Touch LSIG 3p WMP, it combines a 5000 A rated uninterrupted current, three-pole construction and ABB's Ekip Touch electronic trip unit with comprehensive LSIG protection functions.

The E6.2H frame provides substantial short-circuit performance for major industrial, commercial and infrastructure distribution systems. This 5000 A H-performance configuration provides a rated ultimate short-circuit breaking capacity of 100 kA at 440 V AC and a rated short-time withstand current of 100 kA for 1 s, supporting networks with very high prospective fault currents.

The Ekip Touch LSIG electronic trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection, with touchscreen-based programming for convenient protection configuration. Its three-pole withdrawable moving-part (WMP) architecture is designed for use with the appropriate Emax 2 fixed part, supporting isolation, inspection, servicing and replacement within critical switchboard installations.

Comprehensive LSIG Protection for Critical High-Current Distribution

Air circuit breakers such as the ABB Emax 2 E6.2H protect major low-voltage networks against overload, short-circuit and earth-fault conditions. With a 5000 A rated uninterrupted current, 100 kA ultimate short-circuit breaking capacity at 440 V AC and 100 kA short-time withstand capability for 1 s, the 1SDA072616R1 is engineered for critical distribution points requiring substantial current-carrying and fault-management capability.

The Ekip Touch LSIG trip unit provides four complementary protection functions. Long-time protection responds to sustained overloads, short-time protection supports selective coordination, instantaneous protection rapidly interrupts severe short circuits, and earth-fault protection responds to fault current flowing through unintended paths to earth. Combined with touchscreen programming and the E6.2H withdrawable architecture, this configuration provides comprehensive protection and practical maintainability for sophisticated high-current distribution systems.

Typical Applications

• Main incoming protection in high-current low-voltage switchboards.
• Industrial plants with high prospective short-circuit currents.
• Transformer secondary protection.
• High-current distribution feeder protection.
