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