R. STAHL LS Leitungsschutzschalter 8530/1-MCB-STA101-C20-500-2
Art. Nr. 293999
Product Overview
The R. STAHL 8530/1-MCB-STA101-C20-500-2 is a miniature circuit breaker (MCB) from the 8530 series, designed for system technology. These MCBs offer good current limitation for short circuits and high breaking capacity (10, 15, or 25 kA), providing low stress on conductors and high selectivity with upstream fuses. The modular design allows for 1- to 4-pole versions and nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 module widths (TE).
Key features include:
- Trip function according to EN 60947-2
- Energy limitation class 3
- Easy installation and expansion 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
- Lockable with padlocks (accessory) for protection against unintentional reclosing during maintenance
