R. STAHL 8530/1-MCB-STA101-B10-500-2 Line Protection Circuit Breaker
Article No. 293977
System Components for Technology
Product: Line Protection Circuit Breaker
Model: 8530/1-MCB-STA101-B10-500-2
Article No.: 293977
The R. STAHL 8530 series line protection circuit breakers offer excellent current limitation for short circuits and high switching capacities of 10, 15, or 25 kA. They are designed for minimal load on lines and high selectivity to upstream fuses. These components are modular and available in 1 to 4-pole versions with nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 partial units (UP).
Key Features:
- Function: Disconnection according to EN 60947-2
- Energy Limitation Class: 3
- Design: Easy replacement or system extension due to modular circuit breaker design. Simple plug-in mounting on a DIN rail in Ex e enclosures.
- Actuators: Fixed magneto-thermal releases.
- Operation: Ergonomic lever for safe switching on and off.
- Safety: Padlock protection (accessories) prevents re-operation during maintenance.
