R. STAHL 8530/1-MCB-STA101-C16-500-2 Line Protection Circuit Breaker
Product Overview
The R. STAHL 8530/1-MCB-STA101-C16-500-2 is a line protection circuit breaker designed for system technology applications. It offers high current limitation for short circuits and a high switching capacity of 10, 15, or 25 kA, ensuring 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
- Disconnecting function according to EN 60947-2
- Energy limitation class 3
- Easy replacement or extension of existing systems due to modular design
- Simple snap-on mounting on a DIN rail in Ex e enclosures
- Fixed thermal-magnetic releases
- Ergonomic control lever for safe operation and shutdown
- Padlock protection (accessories) prevents re-operation during maintenance
