The 50 kA interrupting capacity at 230 VAC is what sets this part apart — it safely clears high-fault currents in systems with substantial upstream transformer capacity, without requiring a current-limiting upstream breaker. That SCCR headroom matters when you're coordinating protection on a motor control center or a distribution board feeding crushers, conveyors, or pump starters.
Deployment context
The 2-pole format occupies a single module width per pole, so it fits a standard distribution board or sub-panel. Rated for 230 VAC line-to-line or line-to-neutral applications where high inrush currents from motor starters, transformers, or discharge lighting demand a Curve D trip characteristic — the magnetic trip holds through 10–20× rated current, avoiding nuisance trips on startup.
