Model: 8530/1-MCB-STA103N-C10-000-4

Article No.: 293854

Key Features

R. STAHL 8530A Series Circuit Breakers: Offer excellent current limitation in case of short circuits and high breaking capacity (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, available in 1 to 4-pole versions for nominal currents from 0.5–63 A. Maximum mounting capacity is 4.5 division units.
