The Struthers-Dunn/Siemens MRR1ADV-5D is an electromechanical relay designed for use in residential and commercial applications. This type of relay is a time-delay off delay relay, meaning that it is used to control the timing of circuits. It can be used to control the on/off timing of motors and lights, or it can be used to create an electrical delay so that a circuit turns off after a period of time. It features 5 different timing ranges, 0.2-2.5 seconds, 0.5-6.3 seconds, 1.3-18 seconds, 3-50 seconds, and 8-140 seconds. It has a 50VA power rating and a 50A carry current rating. It also features a DIN (Deutsches Institut für Normung) type of mounting for easy installation.
