Product Overview

The R. STAHL 8530 series circuit breakers offer excellent current limitation in case of short circuits and high breaking capacity of 10, 15, or 25 kA. This results in reduced load on electrical lines and high selectivity with respect to upstream fuses. The modules feature a modular structure and are available in 1 to 4 pole versions for nominal currents from 0.5–63 A. The maximum mounting capacity is 4.5 division units.
