R. STAHL 8530/1-MCB-STA103N-C6-000-4 Line Protection Circuit Breaker
Article No. 293853
Product Description
The R. STAHL 8530 series line protection circuit breakers offer excellent current limitation during short circuits and high switching capacities 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 modular units (UP).
Key features include:
- Disconnecting function according to EN 60947-2
- Energy limitation class 3
- Easy replacement or extension of your system due to the modular design of the circuit breakers
- Simple mounting by clipping onto a DIN rail in Ex e enclosures
- Fixed thermal-magnetic releases
- Ergonomic lever for safe switching on and off
- Padlock protection (accessories) prevents re-switching during maintenance operations
