ABB S751 DR E100 1P Selective miniature circuit breaker 100A

The S751DR-E100 is a selective main circuit breaker. It is VDE certified according to IEC / EN 60947-2 and is suitable for use as a group or pre-fuse circuit breaker, which is used in place of NH fuses or other overcurrent protection devices in main distributions or switchgear.

This circuit breaker provides complete selectivity for upstream and downstream protection devices due to the unique energy limitation in case of faults. It does not require a neutral conductor connection and is independent of voltage. No auxiliary energy is required for switching on or off or for the protection function.

The S750DR is intended for din rail mounting and can be placed on a 40mm busbar system using the S750DR-QA busbar adapter. It is particularly suitable for applications in functional buildings, industry, safety-relevant areas, and to ensure high system availability.

Technical specifications include a rated operating voltage of 230 V AC, a rated current of 100 A, and a rated frequency of 50 / 60 Hz. The circuit breaker is also vibration and shock resistant and has a RoHS status according to the EU directive 2015/863 of July 22, 2019.
