Technical Diagrams and Dimensions
The R. STAHL 8530 series circuit breakers offer good current limitation in case of short circuits and a high breaking capacity of 10, 15, or 25 kA. This results in reduced stress on electrical lines and high selectivity with respect to the upstream fuses. The modules are designed with a modular structure and are available in 1 to 4-pole versions for nominal currents from 0.5–63 A. The maximum mounting capacity is 4.5 division units.
Technical Drawings:
Diagram 1: Shows the tripping characteristic curve (I/In) over time (seconds/minutes). The curve indicates the tripping time based on multiples of the rated current for a Type C characteristic.
Diagram 2: Shows the dimensions of the 8530/1; 3 division units. Key dimensions include:
- Width: 83 mm [3.27 in]
- Height: 165 mm [6.50 in]
