R. STAHL LS Leitungsschutzschalter 8530/1-MCB-STA102-C2-500-3
Art. Nr. 272131
Product Overview
The R. STAHL 8530/1-MCB-STA102-C2-500-3 Miniature Circuit Breaker (MCB) is part of the system components range. These MCBs offer good current limiting for short circuits and high breaking capacity of 10, 15, or 25 kA, resulting in reduced stress on conductors and higher 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:
- Trennerfunktion (Isolating function) according to EN 60947-2
- Energy limiting 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 for secure switching
- Protection against re-engagement during maintenance using padlocks (accessory)
