It accepts supply voltage from 24 to 240 V AC/DC, which covers most common control voltages across global panels without needing a separate transformer tap. The relay provides one normally open (NO) and one changeover (CO) auxiliary contact, giving a separate alarm and trip path. An integrated LED display shows operating status at a glance, and the reclosing lockout function prevents automatic restart after a trip — critical for motor protection where manual reset is required by code. The 22.5 mm width fits standard single-module spacing; no extra gap needed between relays. IP20 rated — keep it inside a cabinet, not in the washdown zone.","metaTitle":"Siemens 3RN1022-1DW00 Thermistor Motor Protection, 24-240 V","metaDescription":"Phased-out thermistor motor protection relay, 24-240 V AC/DC, 1 NO + 1 CO, IP20, 22.5 mm.
