R. STAHL LS Leitungsschutzschalter
Model: 8530/1-MCB-STA101-B10-500-2
Article No.: 293977
Product Overview
The R. STAHL 8530/1-MCB-STA101-B10-500-2 miniature circuit breakers offer excellent current limiting capabilities for short circuits, with high switching capacities of 10, 15, or 25 kA. This results in reduced stress on conductors and higher selectivity with upstream fuses. The devices are modularly designed, available in 1- to 4-pole versions, and rated for nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 module units (TE).
Key features include:
- Trennerfunktion according to EN 60947-2
- Energy limitation class 3
- Easy installation and expansion due to modular design
- Simple mounting by snapping onto mounting rails 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
Trip Time Characteristic B:
A graph shows the trip time in seconds versus multiples of the rated current (I/In) for AC and DC. The curve indicates the limit characteristic from a cold state. For AC, the trip times are shown for multiples of the rated current from 1 to 10. For DC, the trip times are shown from 1 to 5.
Dimensional Drawings:
Detailed drawings with dimensions in mm [inch] are provided for the device, showing width, height, and depth. The drawings indicate the device is 8530/1 with 2 module units.
