Electric Motor Temperature Control Bimetallic Strip BW 10A 250V Thermal Protector Switch
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.
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.
• 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
Features
⑴ Small size, easy to install;
⑵ Quick-acting bimetallic strip, with fast response speed;
⑶ Life span is up to 10,000 times or more;
⑷ Anti-vacuum dipping process;
⑸ It can replace SENSATA 17AM 7AM, South Korea SEK ST-22 and other foreign products.
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.

The Model Number Explain
BW-A: The metals outer shell type product.
BW-B: The plastics outer shell type product.
The metals outer shell type the product outer shell take an electricity, should add to insulate a coat.
Precautions
⑴ When using the contact temperature-sensing installation, the product should be close to the installation surface of the controlled appliance.
⑵ Do not crush or deform the plastic or metal shell during installation, so as not to affect the performance.
⑶ Metal shell products with an insulating jacket should not be removed or crushed during installation to avoid leakage and ensure safe use.
⑷ If the product is used in a circuit with a current of no more than 10A, the copper core cross-section should be 0.4-0.75mm and 2 wires should be connected to it.
⑸ The product should be stored in a ventilated, clean, dry, and non-corrosive place where the relative humidity is less than 90% and the ambient temperature is below 40℃.
