Why Choose the ABB 1SDA104529R1 E4.2H/E9 3200 Ekip Touch LSIG Air Circuit Breaker?
The ABB 1SDA104529R1 is a high-performance SACE Emax 2 E4.2H/E9 air circuit breaker designed for protection and control of demanding low-voltage AC power distribution systems operating at 900 V AC. Rated at 3200 A, this four-pole withdrawable moving-part breaker combines the E4.2H/E9 frame with ABB's advanced Ekip Touch LSIG electronic trip unit.
The Ekip Touch LSIG release provides long-time, short-time, instantaneous and earth-fault protection, enabling comprehensive electronic protection against overload, short-circuit and earth-fault conditions. This combination supports coordinated protection in high-current industrial, commercial and infrastructure electrical distribution systems.
The E4.2H/E9 configuration combines a substantial 3200 A current rating with operation at 900 V AC. Its four-pole WMP withdrawable moving-part configuration is designed for use with the corresponding Emax 2 fixed part, allowing the breaker moving part to be isolated and removed for inspection, servicing and maintenance.
