1SDA071936R1 ABB E6.2V 6300 Ekip Touch LSIG 4P FHR Air Circuit Breaker

Why Choose the ABB 1SDA071936R1 Emax 2 Air Circuit Breaker?

The ABB 1SDA071936R1 is a high-performance SACE Emax 2 E6.2V air circuit breaker engineered for protection and switching in demanding low-voltage power distribution systems. Configured as an E6.2V 6300 Ekip Touch LSIG 4p FHR, it combines a rated uninterrupted current of 6300 A with ABB's advanced Ekip Touch LSIG solid-state electronic trip unit.

This four-pole fixed circuit breaker provides comprehensive LSIG protection functions, covering long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection. The Ekip Touch platform adds an intuitive touchscreen interface for protection configuration and monitoring, making the breaker well suited to sophisticated high-current distribution systems requiring dependable protection and selective coordination.

The E6.2V high-performance frame provides a rated ultimate short-circuit breaking capacity of 150 kA at 400–440 V AC, 130 kA at 500–525 V AC and 100 kA at 690 V AC. Its fixed four-pole construction features rear flat horizontal terminals, while a rated short-time withstand current of 100 kA for 1 s and 3 s supports demanding high-fault-current applications.
