R. STAHL 8530/1-MCB-STA101-B16-500-2 Circuit Breaker for Line Protection
Article Number: 293980
Product Overview
The R. STAHL 8530 series line protection circuit breakers, specifically the 8530/1-MCB-STA101-B16-500-2, offer excellent current limitation for short circuits and high switching capacities of 10, 15, or 25 kA. These components are designed for modularity, available in 1 to 4 pole versions with nominal currents from 0.5–63 A, and have a maximum installation capacity of 4.5 installation units (UP).
Key features include:
- Switching-off capacity according to EN 60947-2
- Energy limitation class 3
- Easy replacement or system extension due to modular design
- Simple mounting by clipping onto a DIN rail in Ex e enclosures
- Fixed thermal-magnetic releases
- Ergonomic control lever for safe switching on and off
- Padlock protection (accessories) to prevent re-operation during maintenance
