R. STAHL 8530/1-MCB-STA103-C16-500-4 Circuit Breaker
Article No. 293900
Product Description
The R. STAHL 8530/1-MCB-STA103-C16-500-4 circuit breaker is part of the R. STAHL 8530 series, known for its excellent short-circuit current 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, 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 include:
- Isolating function according to EN 60947-2
- Energy limiting class 3
- Easy replacement or expansion of installations due to modular design
- Simple mounting via DIN rail 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)
The product is certified for use in hazardous areas, including Zone 21/22 with Ex tb/tc enclosure protection.
