Disyuntor
Model: 8530/1-MCB-STA103-C50-500-4
Article No.: 293905
Key Features
- Circuit breaker function according to EN 60947-2
- Energy limitation class 3
- Simple replacement or expansion of installations thanks to modular design of the circuit breaker
- Simple mounting by clipping onto a DIN mounting rail in Ex e enclosures
- Thermally and magnetically adjusted tripping mechanism
- Ergonomic operating lever ensures safe connection and disconnection
- Protection against re-energization during maintenance using padlocks (Accessories)
The R. STAHL 8530 series circuit breakers offer excellent current limitation in case of short circuits and high breaking capacity of 10, 15, or 25 kA. This results in reduced stress on electrical lines and high selectivity with respect to upstream fuses. The modules are designed with a modular structure, available in 1 to 4 pole versions and for nominal currents from 0.5–63 A. The maximum mounting capacity is 4.5 division units.
