High Temperature Normally Close Open 10A 250V 200C BW Thermal Switch for Heating Heater
Description
BW series thermal protector is to adopt a certain geometry of bimetallic strip, without auxiliary mechanism, only by the bimetallic strip themselves feeling gentle heating current, rapid changes in the state of the bimetallic element, direct drive contact automatic cutting and processing circuit, overheat and overload protection.
Product Advantages
BW Thermal Protector Up To 250°C
In general, the highest temperature is 160°C for BW thermal protector. But our BW thermal protector can up to 250C. It has the characteristics of small size, rapid action, precise temperature control, large control current and long service life.
Features
• Sealed with imported high temperature 300C epoxy resin
• Gold plated internal silver contacts
• 250C Teflon wire with UL certification
• Shrapnel adopts high temperature resistant and high strength beryllium copper process
Application
BW Series thermal protector has small, nimble, long life and other characteristics, widely used in a variety of tubular motor, induction cooker, vacuum cleaners, coils, transformers, electric heaters, ballast, electric appliances, fluorescent lamp ballasts, auto motor, IC and general electrical equipment overheating over current double protection.
