R. STAHL 8530/1-MCB-STA102-C40-500-3 Line Protection Circuit Breaker
Article Number: 272140
Product Overview
The R. STAHL 8530 series line protection circuit breakers, specifically the 8530/1-MCB-STA102-C40-500-3 model, offer excellent current limitation for short circuits and high switching capacities of 10, 15, or 25 kA. These components ensure minimal load on lines and high selectivity with upstream fuses. They are modularly designed and available in 1 to 4 pole versions with nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 partial units (UP).
Key features include:
- Isolation function according to EN 60947-2
- Energy limitation class 3
- Easy replacement or extension of systems due to modular design
- Simple mounting by clipping onto a DIN rail in Ex e enclosures
- Fixed thermal-magnetic releases
- Ergonomic operating lever for safe switching on and off
- Padlock protection (accessories) prevents re-operation during maintenance
