Metal or plastic Thermal overload protector for pumps
General Introduction
BW series thermal protector with small size, shell insulation, quick action,long life and other characteristics, they are widely used in all kinds of motor, induction cooker, vacuum cleaners, coils, transformers, electric heaters, ballast, electric appliances, fluorescent lamp ballasts, auto motor, IC and general electrical equipment over-current, over-heating dual protection.
BW series thermal protector is a bimetal using certain geometry without auxiliary institutions, only by bimetallic strip their own sense of mild heating current, rapid changes in the state of bimetallic element, which drive contact automatic cutting and processing circuit directly, to reach overheat protection, overload protection.

Cautions:
1. ABS plastic Shell protector should not be used for more than 130 ºC high temperature environment for a long time, in order to prevent causing plastic deformation of the protector.
2. Shall not be in strong acid, alkali and other strong corrosive environment for long time use.
3.Protectors should be installed in a protected object temperature sensitive point, the heat surface should be effectively protected in close contact with components or directly to protected area.
4.During the installation process, in order to prevent the casing deformation or damage and make the protector performance change, attention should be paid to the following: sharp tools shall not be used for protector for pressure;Shall not use gravity mauling protector;
5.Connection method using arc welding process, the welding current is not through the thermal protector, otherwise excessive current can cause direct damage by the action of thermal protection contact.
