R. STAHL Circuit Breaker 8530/1-MCB-STA101-B10-500-2
Article No. 293977
Product Description
The R. STAHL 8530 series circuit breakers offer excellent short-circuit limitation and high breaking capacity (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, are available in 1 to 4-pole versions, and support nominal currents from 0.5–63 A. The maximum mounting width is 4.5 division units.
Key features include:
- Circuit breaker 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 for secure connection and disconnection
- Protection against reconnection during maintenance using padlocks (Accessories)
