Disjoncteur Disjonct. protection de ligne
The R. STAHL 8530 series 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 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 (PU).
Key Features:
- 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 control lever for safe switching on and off
- Padlock protection (accessories) prevents restarting during maintenance operations
