ABB 2CDH784010R0322 Circuit Breaker S 750 DR

Description

• The ABB 2CDH784010R0322 Selective Main Circuit-Breakers of the S 750 DR series are cutting-edge circuit protection devices designed to meet the most demanding requirements in electrical distribution systems. These circuit-breakers are engineered based on DIN VDE 0641-21 standards and feature a voltage-independent operating principle, setting them apart from traditional circuit-breakers.

• The standout features of these circuit-breakers is their ability to operate without relying on a control circuit to make or break contact (SHU). This characteristic ensures their suitability for use in energy distribution systems with the highest availability requirements. They are particularly well-suited for critical applications where uninterrupted power supply is essential.

• These circuit-breakers offer total selectivity to downstream Miniature Circuit Breakers (MCBs), ensuring that in the event of a fault, only the affected circuit is disconnected while the rest of the electrical distribution system continues to operate without disruption.
