R. STAHL LS Leitungsschutzschalter 8530/1-MCB-STA103N-C6-000-4

Art. Nr. 293853

Product Overview

The R. STAHL 8530/1-MCB-STA103N-C6-000-4 is a miniature circuit breaker (LS Leitungsschutzschalter) designed for system technology applications. It offers good current limitation for short circuits and high switching capacity of 10, 15, or 25 kA, ensuring low load on lines 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:

Trennerfunktion according to EN 60947-2
Energy limitation class 3
Easy installation or expansion of systems with a 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-switching during maintenance via padlocks (accessory)
