Why Choose the ABB S752DR-K16 Selective Main Circuit Breaker?
The ABB S752DR-K16 is a selective 2-pole main circuit breaker (SMCB) designed to provide dependable overload and short-circuit protection in low-voltage electrical distribution systems where selectivity and continuity of supply are important. Part of the ABB S750 DR series, it combines selective protection with a voltage-independent operating principle and convenient DIN rail installation.
Featuring a 16 A rated current and Type K selective characteristic, the S752DR-K16 is designed for coordinated protection with suitable downstream miniature circuit breakers. ABB's S750 DR selective protection concept enables total short-circuit selectivity to downstream MCBs without additional configuration, helping isolate faults at the appropriate level while maintaining supply to unaffected circuits.
The S752DR-K16 provides a short-circuit breaking capacity of 25 kA and uses a robust two-pole construction for coordinated switching and protection. Its selective operating characteristics make it suitable for appropriately engineered commercial, industrial and building distribution systems where reliable group protection and continuity of service are important.
