R. STAHL LS Leitungsschutzschalter

8530/1-MCB-STA102-B25-500-3

Art. Nr. 272128

Product Overview

The R. STAHL 8530/1-MCB-STA102-B25-500-3 is a miniature circuit breaker designed for system technology applications. It offers good current limitation for short circuits and high switching capacity of 10, 15, or 25 kA, resulting in low load on conductors and high selectivity to upstream fuses. The modular design allows for 1- to 4-pole versions and nominal currents from 0.5–63 A, with a maximum installation capacity of 4.5 modules (TE).

Key features include:

Disconnector function according to EN 60947-2
Energy limitation class 3
Easy installation or expansion of systems due to modular design
Simple mounting by snapping onto top-hat rails in Ex e enclosures
Fixed thermal and magnetic trip units
Ergonomically shaped operating lever for secure switching
Protection against re-engagement during maintenance using padlocks (accessory)
