R. STAHL LS Leitungsschutzschalter 8530/1-MCB-STA103-C6-000-3

Art. Nr. 272175

Product Overview

The R. STAHL 8530/1-MCB-STA103-C6-000-3 is an LS 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 lower stress on conductors and higher selectivity to upstream fuses. The modular design allows for 1- to 4-pole versions with nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 modules (TE).

Key features include:

Trennerfunktion according to EN 60947-2
Energy limitation class 3
Easy replacement or expansion of installations due to modular design
Simple mounting by snapping onto a mounting rail in Ex e enclosures
Fixed thermal and magnetic trip settings
Ergonomically shaped operating lever for secure switching
Protection against re-switching during maintenance using padlocks (accessory)
