Why Choose the ABB 1SDA128897R1 E4.3V 3200 Ekip Aware LSIG Air Circuit Breaker?
The ABB 1SDA128897R1 is a high-performance SACE Emax 3 E4.3V air circuit breaker (ACB) designed for protection and control of demanding low-voltage power distribution systems. Rated at 3200 A, this four-pole circuit breaker combines ABB's E4.3 frame with the advanced Ekip Aware LSIG electronic trip unit for comprehensive electrical protection.
The Ekip Aware LSIG trip unit provides long-time (L), short-time (S), instantaneous (I) and ground-fault (G) protection, enabling the breaker to protect electrical installations against overloads, short circuits and ground faults. The E4.3V performance level provides a rated ultimate short-circuit breaking capacity of 150 kA at 440 V AC and a short-time withstand current of 100 kA for 1 s.
This configuration is a four-pole fixed circuit breaker with orientable rear terminals (HR), making it suitable for high-current switchboards and power distribution assemblies where robust protection, installation flexibility and high fault-breaking performance are required.
