NettetContact design The model TFS35 bimetal temperature switch can be delivered in two contact designs.. A Normally Closed (NC = closed in the normal state) opens a circuit and shuts down the machinery.. A Normally Open (NO = open in the normal state) closes a circuit on reaching the switching temperature, in order that, for example, a fan or … NettetMotor protection switch. The temperature of the winding is determined by the energy losses in the electric motor as well as other factors. The “copper losses” are the main contributor to the heat generation. The copper losses are in proportion to the square of the current (Pcu = I2 x R).
