It accepts a universal control supply of 24-240 V AC/DC (50/60 Hz), so it drops into panels regardless of whether the control voltage is 24 VDC or 230 VAC — no separate supply module needed. The relay provides one normally-open and one normally-closed auxiliary contact (1 NO + 1 NC), which is the standard arrangement for fail-safe trip signalling: the NC contact opens on a fault condition, the NO closes to indicate the alarm. It also includes a reclosing lockout feature, meaning after a trip the relay stays latched until manually reset — no automatic restart that could surprise maintenance. At 45 mm wide, it takes up one standard module slot — no panel re-spacing needed. The spring-loaded terminals accept 0.2-2.5 mm² wire; strip length should be 8-10 mm for a clean connection. The part carries a substance prohibition date of 07/01/2006, which aligns with the original EU RoHS directive (RoHS 1). No UL, CSA, or CE marks are listed on this record, but the 3RN family is typically CE-marked for the European market. For compliance documentation, request the manufacturer's declaration of conformity and RoHS certificate with your RFQ.","metaTitle":"Siemens 3RN1062-2CW00 Thermistor Motor Protection, 24-240 V","metaDescription":"Siemens 3RN1062-2CW00 thermistor motor protection relay, 1 NO + 1 NC, 24-240 V AC/DC, IP20, 45 mm wide.
