R. STAHL 8530/1-MCB-STA101-C16-500-2 Circuit Breaker
Article No. 293997
System Components for Technology
The R. STAHL 8530 series circuit breakers offer excellent current limitation in short-circuit situations and high breaking capacities of 10, 15, or 25 kA. This results in reduced stress on electrical lines and improved selectivity with upstream fuses. The modules feature a modular design, available in 1 to 4-pole versions for nominal currents from 0.5–63 A. The maximum mounting capacity is 4.5 division units.
Key Features:
- Disconnecting function according to EN 60947-2
- Energy limitation class 3
- Easy replacement or expansion of installations due to modular design
- Simple mounting via DIN rail snap-in in Ex e enclosures
- Fixed thermal and magnetic trip settings
- Ergonomic operating lever ensures safe connection and disconnection
- Protection against re-closing during maintenance using padlocks (Accessories)
