The 201A is a three-phase voltage monitor designed to protect 190-480 V ac, 50/60 Hz motors by detecting faults such as phase loss, voltage unbalance, phase reversal, and overvoltage. It auto-senses input voltage and features a single LED for fault diagnostics. The device has a SPDT output relay rated at 10 A at 240 V ac and a 2-second trip delay for unbalance and phasing faults, and 4 seconds for high/low voltage faults. It operates from -20° to 70 °C, with a maximum power draw of 5 W and meets IEC 61000-4-2, IEC 61000-4-4, IEC 61000-4-5, and ANSI/IEEE C62.41 surge immunity levels. Measuring 44.45 mm H × 60.33 mm W × 104.78 mm D with socket, it mounts on DIN-rail or surface using the OT08PC socket and is UL 508 certified.
