R. STAHL LS Miniature Circuit Breaker

Model: 8530/1-MCB-STA101-C40-500-2

Article Number: 294003

Product Overview

The R. STAHL 8530 series of miniature circuit breakers offer excellent current limiting capabilities and high breaking capacity (10, 15, or 25 kA). This results in reduced stress on connected lines and higher selectivity with upstream fuses. The devices are modularly designed and available in 1- to 4-pole versions for nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 module widths (TE).

Key features include:
