Struthers-Dunn 219DXB119NE is a nuclear safety relay from the 219 Series designed for safety-critical switching in nuclear or safety-related control circuits. It uses a 120 VAC coil rated for 50/60 Hz and comes in a plug-in, 14-pin package with a polycarbonate cover for rugged installations. The contact configuration combines four normally open poles (4PST-NO) with a double-pole, normally closed pair (DPST-NC), and it is rated for 10 A at 120 VAC. This model is the NE variant, indicating its nuclear-safety designation within Struthers-Dunn's catalog, and is built to meet the reliability requirements typical of Struthers-Dunn's nuclear safety line.
