Product Overview
The R. STAHL 8530 series miniature circuit breakers offer excellent current limitation for short circuits and a high breaking capacity of 10, 15, or 25 kA. This results in reduced stress on conductors and higher selectivity to upstream fuses. The components are modularly designed and available in 1- to 4-pole versions for rated currents from 0.5–63 A. The maximum installation capacity is 4.5 module widths (TE).
