Model: 8530/1-MCB-STA103-B6-000-3
Product Description
The R. STAHL 8530 series line protection circuit breakers offer excellent current limitation during short circuits and high switching capacity 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 with nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 partial units (UP).
Key Features
- Functionality: Sectioning according to EN 60947-2
- Energy Limitation Class: 3
- Modular Design: Easy replacement or extension of systems.
- Mounting: Simple snap-on mounting on a DIN rail in Ex e enclosures.
- Tripping: Fixed magneto-thermal releases.
- Operation: Ergonomic lever for safe switching on and off.
- Safety: Padlock protection (accessories) prevents re-operation during maintenance.
