R. STAHL 8530/1-MCB-STA102-C1-500-3 Line Protection Circuit Breaker
Article Number: 267203
Product Overview
The R. STAHL 8530/1-MCB-STA102-C1-500-3 is a line protection circuit breaker designed for system technology. It offers high current limitation for short circuits and a high switching capacity of 10, 15, or 25 kA, ensuring low line load and high selectivity with 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 installation units (UP).
Key Features
- Disconnecting function according to EN 60947-2
- Energy limitation class 3
- Easy replacement or expansion of your system due to modular design
- Simple snap-on mounting on a DIN rail in Ex e enclosures
- Fixed magneto-thermal releases
- Ergonomic control lever for safe switching on and off
- Padlock protection (accessories) prevents re-switching during maintenance operations
