R. STAHL 8530/1-MCB-STA101-C10-500-2 Line Protection Circuit Breaker
This document provides technical specifications for the R. STAHL 8530/1-MCB-STA101-C10-500-2 line protection circuit breaker.
Product Overview
The R. STAHL 8530 series 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 include:
- Disconnecting function according to EN 60947-2
- Energy limitation class 3
- Easy replacement or system extension due to modular design
- Simple mounting by clipping onto a DIN rail in Ex e enclosures
- Fixed thermal-magnetic releases
- Ergonomic control lever for safe operation and shutdown
- Padlock protection (accessories) to prevent restarting during maintenance
