R. STAHL LS Leitungsschutzschalter (Miniature Circuit Breaker)

Model: 8530/1-MCB-STA103N-C16-100-4

Article Number: 293876

Product Overview

The R. STAHL 8530/1-MCB-STA103N-C16-100-4 is a miniature circuit breaker designed for system technology applications. It offers good current limiting for short circuits and high breaking capacity (10, 15, or 25 kA), providing low load on lines and high selectivity to upstream fuses. The modular design allows for 1- to 4-pole configurations and nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 module widths (TE).
