Thermal overload protector is a bimetal disc specially designed for a specific rating of temperature. This provides a complete protection to single phase motors, transformers, pumps and all domestic appliances from damage due to overheating. These can be embedded into the motors or transformer winding or any other equipment. The protectors are selected according to the safe temperature of the motor or the equipment to prevent damage due to overheating. Whenever the equipment gets heated to the switching temperature of the protector, the contact of the protector changes it`s status and the equipment can be switched off to avoid further heating and burning.
The protectors are available in different current ratings and wide range of switching temperatures from 60 deg. To 160 deg. C. The nc type protectors are connected directly in series with the winding of motors or primary transformers. Whenever the winding gets heated beyond the acceptable limit, the contact of the protector opens and the equipment [motor or transformer] gets switched off. The protector contact resets automatically 40 deg. C. Below the tripping temperature to avoid the chattering effect. This is a most economical and sure shot solution for protecting
The equipments from damaging due to overheating.
Each top has a bimetal disc specially designed for that rating. Every top is calibrated and checked twice for opening and resetting temperature. Thus consistent performance over required life cycles is achieved.
