R. STAHL 8530/1-MCB-STA101-C40-500-2 Line Protection Circuit Breaker
Article Number: 294003
Product Overview
The R. STAHL 8530 series line protection circuit breakers, specifically the 8530/1-MCB-STA101-C40-500-2 model, 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 with upstream fuses. These 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 include:
- Switch-disconnector 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 magneto-thermal trip units
- Ergonomic lever for safe operation and shutdown
- Padlockable (accessories) to prevent re-operation during maintenance
