What the ATEX certification means for deployment
The PTB (ATEX) certification means this relay is approved for use in explosive atmospheres where gas or dust hazards are present, per the ATEX directive. It integrates into the drive's motor thermal protection circuit, monitoring PTC thermistors embedded in the motor windings.
