LS Miniature Circuit Breaker

Model: 8530/1-MCB-STA102-C40-500-3

Article No.: 272140

Product Overview

The R. STAHL LS Miniature Circuit Breakers of the 8530 series offer good 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 with upstream fuses. The components are modularly designed, available in 1- to 4-pole versions, and rated for nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 module widths (TE).
