Lifecycle and Replacement
The 3RN1011-1CK00 is a phased-out product. The preferred successor is the 3RN2011-1BW30 thermistor motor protection evaluation unit with manual reset, 1 NO + 1 NC, 230/110 V AC, screw terminal.
IP20 protection means it is suitable for installation inside a control cabinet only — not for field mounting where moisture or dust ingress is a concern.
As a phased-out part, the 3RN1011-1CK00 is sourced through last-time-buy and surplus channels. A declaration of conformity covering RoHS and REACH (substance prohibition date 07/01/2006) is available with the documentation package. For new designs or BOM freeze, the successor 3RN2011-1BW30 should be specified to avoid future obsolescence risk.
