The Macromatic THR-3836U is a programmable Time Delay Relay. This encapsulated, multi-range, multi-voltage relay has an input voltage of 24-240V AC and a 12-125V DC. It is a multi-function unit with 4 different settings. The THR3836U accommodates pilot duty and fractional HP loads. The time delay can be changed either on the unit or remotely. Featuring dimensions of 2" x 2", the encasement allows it to be used in more extreme conditions. The functions on the THR-3836U differ from the THR-3816U. DIP switches allow the user to select the settings. Note: Image is an approximation. Actual part may differ.
