R. STAHL LS Leitungsschutzschalter 8530/1-MCB-STA103-B6-000-3
Art. Nr. 272160
Product Overview
The R. STAHL 8530/1-MCB-STA103-B6-000-3 LS Miniature Circuit Breaker is designed for system technology applications. It offers good current limitation for short circuits and high breaking capacity (10, 15, or 25 kA), leading to reduced stress on cables and higher selectivity with upstream fuses. The modular design allows for 1- to 4-pole configurations and current ratings from 0.5–63 A, with a maximum installation capacity of 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 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)

Technical Drawings
(Note: Diagrams are illustrative and subject to change. Refer to original documentation for precise details.)
Tripping Characteristic B Curve:
A graph illustrates the tripping time in seconds against multiples of the rated current (I/In) for AC and DC. The curve shows the typical response for a Type B breaker, indicating the threshold for tripping under overload and short-circuit conditions. The graph includes a limit curve from a cold state.
Dimensional Drawings:
Detailed drawings show the dimensions of the circuit breaker in millimeters and inches. Key dimensions include width, length, and installation depth. The drawings indicate the modularity (e.g., 8530/1; 3 division units) and mounting details.
