Further Details:
The S750DR series in 80 and 100A are selective main circuit breakers (SH breakers), VDE certified according to IEC / EN 60947-2, and are used as group or backup circuit breakers instead of NH fuses or other overcurrent protection devices in switchgear or distribution systems. They provide complete selectivity for upstream and downstream protective devices due to their unique energy limitation in case of a fault. The S750DR does not require a neutral conductor connection; they are voltage-independent. No auxiliary power is needed for switching on or off or for the protection function. The design ensures reliable fulfillment of the protection function, regardless of network disturbances or network form. The S750DR is designed for mounting on DIN rails. The 3-pole devices can be connected to a 40mm busbar system using the busbar adapter S750DR-QA.

Application: Purpose-built, industry, safety-critical areas, and to ensure high system availability.
