R. STAHL 8530/1-MCB-STA102-B16-500-3 Circuit Breaker
Article Number: 272126
Product Overview
The R. STAHL 8530/1-MCB-STA102-B16-500-3 circuit breaker is a component for system technology. It features a modular design for easy installation and expansion, suitable for DIN mounting in Ex e enclosures. The device offers fixed thermal and magnetic tripping and an ergonomic operating lever for safe connection and disconnection. It also includes protection against reconnection during maintenance via padlocks (accessories).
These circuit breakers offer good current limitation in case of short circuits and high breaking capacities of 10, 15, or 25 kA, leading to reduced stress on electrical lines and improved selectivity with upstream fuses. They are available in 1 to 4-pole versions for nominal currents from 0.5–63 A, with a maximum mounting width of 4.5 division units.
