The 201A-AU is a three-phase voltage monitor designed to protect 190-480 V ac, 50/60 Hz motors by detecting faults such as phase loss, overvoltage, undervoltage, voltage unbalance, and phase reversal. It automatically selects between 200 V and 400 V ranges, features adjustable trip delay (1-30 seconds), adjustable restart delay (1-500 seconds or manual), and a user-settable voltage unbalance trip point of 2-8%. The unit includes a single LED for fault diagnostics and has a 1-Form C relay with a 10 A, 240 V ac contact rating. It mounts via DIN-rail or surface mount using the OT08PC socket, and measures 44.45 mm H x 60.325 mm W x 104.775 mm D. Operating temperature ranges from -40°C to 70°C. It meets UL 508, IEC 61000-4-2 (Level 3), IEC 61000-4-4 (Level 3), IEC 61000-4-5 (Level 3 line-to-line, Level 4 line-to-ground), and ANSI/IEEE C62.41 surge standards.
