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