Model: 8530/1-MCB-STA102-B20-000-2
Art. No.: 293919
Product Description
The R. STAHL 8530/1-MCB-STA102-B20-000-2 circuit breaker is designed for systems technology, offering good current limitation in case of short circuits and high breaking capacity (10, 15, or 25 kA). This results in reduced electrical line loading and high selectivity with respect to upstream fuses. The modules feature a modular design, available in 1 to 4 pole versions and for nominal currents from 0.5–63 A. Maximum mounting capacity is 4.5 division units.
Key Features:
- 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-on in Ex e enclosures
- Fixed thermal and magnetic trip adjustment
- Ergonomic operating lever for safe connection and disconnection
- Protection against re-energization during maintenance using padlocks (Accessories)
