R. STAHL 8530/1-MCB-STA101-C6-500-2 Circuit Breaker

Article Number: 293994

Product Overview

The R. STAHL 8530/1-MCB-STA101-C6-500-2 circuit breaker is part of the system technology components. It offers high current limitation in case of short circuits and a high breaking capacity of 10, 15, or 25 kA, resulting in reduced load on electrical lines and high selectivity with upstream fuses. The modular design allows for 1 to 4 pole configurations and nominal currents from 0.5–63 A. The maximum mounting width is 4.5 division units.

Key features include:

Function as a separator according to EN 60947-2
Energy limitation class 3
Simple replacement or expansion of installations due to modular design
Easy mounting via DIN rail in Ex e enclosures
Adjustable thermal and magnetic tripping
Ergonomic operating lever for safe connection and disconnection
Protection against reclosing during maintenance using padlocks (Accessories)
