R. STAHL 8530/1-MCB-STA102-C0.5-000-2 Line Protection Circuit Breaker
Article Number: 293963
Product Description
The R. STAHL 8530 series line protection circuit breakers offer excellent current limitation during short circuits with a high switching capacity of 10, 15, or 25 kA. This ensures minimal load on lines and high selectivity to upstream fuses. The components 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:
- Disconnecting function according to EN 60947-2
- Energy limitation class 3
- Easy replacement or extension of systems due to modular design
- Simple plug-in mounting on a DIN rail in Ex e enclosures
- Fixed magneto-thermal releases
- Ergonomic control lever for safe operation and shutdown
- Padlockable (accessories) to prevent re-operation during maintenance
