R. STAHL LS Leitungsschutzschalter 8530/1-MCB-STA103N-C10-000-4
Art. Nr. 293854
Product Overview
The R. STAHL 8530 series of miniature circuit breakers offer excellent current limitation for short circuits and high breaking capacity of 10, 15, or 25 kA. This results in reduced stress on conductors and higher selectivity with upstream fuses. The modules are designed for modularity, available in 1- to 4-pole versions, and rated for nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 module units (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 top-hat rail in Ex e enclosures
- Fixed thermal and magnetic trip units
- Ergonomically shaped operating lever for secure switching
- Protection against re-switching during maintenance using padlocks (accessory)
