R. STAHL LS Leitungsschutzschalter 8530/1-MCB-STA103-B16-500-4
Article No.: 293886
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 cables and higher selectivity with upstream fuses. The modules are designed for modularity, available in 1- to 4-pole versions, and for rated currents from 0.5–63 A. The maximum installation capacity is 4.5 modules (TE).
Key features include:
- Tripping function according to EN 60947-2
- Energy limitation class 3
- Easy replacement or expansion of installations 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 ensures safe switching on and off
- Protection against re-switching during maintenance using padlocks (accessory)
