R. STAHL 8530/1-MCB-STA101-B16-500-2 Circuit Breaker
Article No.: 293980
System Components - Circuit Breaker
The R. STAHL 8530 series circuit breakers offer excellent short-circuit current limitation and high breaking capacities of 10, 15, or 25 kA. This results in reduced stress on electrical lines and high selectivity with respect to upstream fuses. The modules feature a modular design and are available in 1 to 4-pole versions with nominal currents from 0.5–63 A. The maximum mounting capacity is 4.5 division units.
Key Features:
- Disconnector function according to EN 60947-2
- Energy limitation class 3
- Simple replacement or expansion of installations due to the modular design of the circuit breaker.
- Simple mounting by clipping onto a DIN mounting rail in Ex e enclosures.
- Thermally and magnetically tripped, with fixed settings.
- Ergonomic operating lever ensures safe connection and disconnection.
- Protection against reconnection during maintenance using padlocks (Accessories).
