Thiim – PAD 3802 ADK – Phase Failure & Asymmetry Monitoring Relay 440 VAC

The Thiim PAD 3802 ADK (also referenced as PAA 3802 FNK) is a DIN‑rail mountable phase/frequency monitor relay designed to detect phase failure, asymmetry, and phase sequence errors in three-phase systems up to 440 VAC. Manufactured in Denmark, it safeguards motors and electrical equipment by de-energizing control circuits under fault conditions.
