R. STAHL 8530/1-MCB-STA102-B16-500-3 Line Protection Circuit Breaker
Article Number: 272126
Product Overview
The R. STAHL 8530 series line protection circuit breakers offer excellent current limitation in case of short circuits and high switching capacity of 10, 15, or 25 kA. This ensures minimal load on lines and high selectivity to upstream fuses. The components are modular and available in 1 to 4 pole versions for nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 partial units (UP).
Key features include:
- Disconnection according to EN 60947-2
- Energy limitation class 3
- Easy replacement or extension of your system thanks to the modular design
- Simple mounting by clipping onto a DIN rail in Ex e enclosures
- Fixed magneto-thermal releases
- Ergonomic operating lever for safe operation and shutdown
- Padlock protection (accessories) prevents restarting during maintenance
