R. STAHL 8530/1-MCB-STA102-B10-000-2 Line Protection Circuit Breaker
Article No.: 293915
Product Description
The R. STAHL 8530/1-MCB-STA102-B10-000-2 line protection circuit breakers offer excellent current limitation for short circuits and high switching capacities of 10, 15, or 25 kA. This ensures minimal load on lines and high selectivity with upstream fuses. The components are modularly designed and available in 1 to 4-pole versions for nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 installation units (UP).
Key Features:
- 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 thermal-magnetic releases
- Ergonomic lever for safe operation and shutdown
- Padlock protection (accessories) prevents re-operation during maintenance
