T  Thermal relay
 
Application
 
The relay is suitable for using in the power circuits up to rated voltage 660V,rated  current 500A 50Hz or 60Hz for overload and loss of phase protection or three phase induxtion motor and often sombined with B serise AC contactor into
magnetic starter. GT16 & GT25 thermal relays have a friction trip operating mechanism with loss of phase runing protection, pullback spring trip operating mechanism (jump mechanism) with loss of phase protection for GT85 & GT45, back pack jump mechanism for GT170 & GT105, main circuit with instrument transformer jump mechanism with loss of phase for GT250 & GT370.
