Disjoncteur Disjonct. protection de ligne

The R. STAHL 8530 series line protection circuit breakers offer good current limitation for short circuits and high switching capacities of 10, 15, or 25 kA. This ensures minimal load on lines and high selectivity to upstream fuses. The components are modular and available in 1 to 4-pole versions with nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 partial units (UP).
