ABB 2CDH781010R0822 Circuit Breaker

Description

• The ABB 2CDH781010R0822 Selective Main Circuit-Breaker (SMCB) belongs to the renowned S 750 DR series, renowned for its selective and dependable performance. These SMCBs are engineered in accordance with DIN VDE 0641-21 standards and operate based on a voltage-independent operating principle. This unique feature distinguishes them from conventional circuit breakers as they do not rely on a control circuit to establish or interrupt contact (SHU). Consequently, they are exceptionally well-suited for integration into energy distribution systems that demand the highest levels of availability.

• The standout features of these SMCBs is their capability for total selectivity when connected to downstream Miniature Circuit Breakers (MCBs). Furthermore, they exhibit exceptional selectivity when connected to upstream protective devices, thanks to their unique current limiting selectivity. This remarkable selectivity ensures precise isolation of faulty segments of the circuit without affecting the rest of the system in the event of a fault or overload. This minimizes downtime and maximizes the overall availability of the system.
