R. STAHL 8530/1-MCB-STA103-C16-000-3 Circuit Breaker
This document provides technical specifications for the R. STAHL 8530/1-MCB-STA103-C16-000-3 circuit breaker, part number 272178.
Product Overview
The R. STAHL 8530 series circuit breakers are designed for systems technology and offer good current limitation in case of short circuits with a high breaking capacity of 10, 15, or 25 kA. This results in reduced load on electrical lines and high selectivity with respect to connected fuses. The modules feature a modular structure and are available in 1 to 4-pole versions for nominal currents from 0.5–63 A. The maximum mounting capacity is 4.5 division units.
Key features include:
- Separator function according to EN 60947-2
- Energy limitation class 3
- Simple substitution or expansion of installations due to modular design
- Easy mounting via DIN mounting rail in Ex e enclosures
- Fixed thermal and magnetic tripping adjustment
- Ergonomic operating lever for safe connection and disconnection
- Protection against re-energization during maintenance using padlocks (accessories)
