R. STAHL LS Leitungsschutzschalter 8530/1-MCB-STA103N-C32-000-4
Art. Nr. 293859
Product Overview
The R. STAHL 8530 series 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 modular design allows for 1- to 4-pole versions and nominal currents from 0.5–63 A, with a maximum installation capacity of 4.5 modules (TE).
Key features include:
- Trennerfunktion (Isolating 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 for secure switching
- Protection against re-closing during maintenance using padlocks (accessory)

Technical Drawings and Diagrams
Trip Characteristic Curve: A graph shows the tripping time in seconds and minutes against multiples of the rated current (I/In) for AC and DC. The curve is labeled 'C' for tripping characteristic and indicates a limit curve from a cold state.
Dimensional Drawings: Multiple views illustrate the dimensions of the circuit breaker in millimeters and inches. The drawings show the overall width, length, depth, and mounting details, including the 4-module width (8530/1; 4 Teilungseinheiten).
