R. STAHL Circuit Breaker 8530/1-MCB-STA103-C10-000-3
Article No. 272176
Product Description
The R. STAHL 8530 series circuit breakers offer excellent current limitation in case of short circuits and high breaking capacity (10, 15, or 25 kA). This results in reduced load on electrical lines and high selectivity with respect to upstream fuses. The modules feature a modular design, available in 1 to 4 pole versions, and nominal currents from 0.5–63 A. The maximum mounting width is 4.5 division units.
Key Features:
- Disconnector function according to EN 60947-2
- Energy limitation class 3
- Simple replacement or expansion of installations thanks to the modular design of the protective switch.
- Easy mounting by clipping onto a DIN mounting rail in Ex e enclosures.
- Fixed thermal and magnetic trip adjustment.
- Ergonomic operating lever ensures safe connection and disconnection.
- Protection against re-closing during maintenance using padlocks (Accessories).

Technical Diagrams
Trip Time Characteristic Curve: The document includes a graph illustrating the trip time characteristic curve for the circuit breaker, showing the relationship between the multiple of the rated current (I/In) and the trip time in seconds and minutes. It specifies the characteristic as 'C' for both AC and DC applications.
Dimensional Drawings: Detailed dimensional drawings are provided for the circuit breaker (8530/1, 3 division units), showing measurements in millimeters and inches. These include width, height, depth, and mounting dimensions.
