R. STAHL 8530/1-MCB-STA102-B16-000-2 Line Protection Circuit Breaker
Article Number: 293918
Product Overview
The R. STAHL 8530 series line protection circuit breakers (MCBs) offer robust current limitation for short circuits with high switching capacities of 10, 15, or 25 kA. These components are designed for minimal line load and high selectivity with upstream fuses. They feature a modular design, are available in 1 to 4-pole versions, and support nominal currents from 0.5 to 63 A. The maximum installation capacity is 4.5 installation units (UP).
Key features include:
- Switch-disconnector function according to EN 60947-2
- Energy limitation class 3
- Easy replacement or system extension due to modular design
- Simple mounting by clipping onto a DIN rail in Ex e enclosures
- Fixed magneto-thermal releases
- Ergonomic operating lever for safe operation and shutdown
- Padlock protection (accessories) prevents re-operation during maintenance
