Article No. 293859
The R. STAHL series 8530 line protection circuit breakers offer good current limitation during short circuits and a high switching capacity of 10, 15, or 25 kA. This ensures minimal load on lines and high selectivity with 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:
- Disconnecting function according to EN 60947-2
- Energy limitation class 3
- Easy replacement or extension of your system thanks to the modular design of the circuit breakers
- Simple mounting by clipping onto a DIN rail in Ex e enclosures
- Fixed magneto-thermal releases
- Ergonomic lever for safe activation and deactivation
- Padlock protection (accessories) prevents re-operation during maintenance
