ABB 2CDH783010R0822 S753DR-E100 Circuit breaker 3-phase 100 A

The S750DR in 80 and 100A are selective main circuit breakers (SHSwitch) VDE certified according to IEC / EN 60947-2 and are used as group or backup machines instead of NH fuses or other overcurrent protection devices in main distribution or switchgear. They offer complete selectivity for upstream and downstream protective devices due to the unique energy limitation in the event of a fault.
The S750DR does not need a neutral wire connection, they are voltage-independent. Neither the power supply is required for switching on or off, nor for the protection function. The design ensures reliable fulfillment of the protection function, regardless of mains disturbances or network shape.
The S750DR is designed for mounting on top hat rails. The 3-pin devices can be set to a 40mm busbar system using the S750DR-QA bus bar adapter.
Application: Functional construction, industry, safety-relevant areas and to ensure high plant availability. For example, in structural facilities for human collections (DIN VDE 0100-718) and in medically used areas (DIN VDE 0100-710).
