Plastic shell, Snap action thermal protector , automatic reset type with UL,VDE, CB, CCC , Rohs compliant

Work principle:

BW-A1D thermal protector is a temperature automatic response devide and is connected in series to the winding of motor. The contacts open on temperature rise and reset after the temperature drops down.

Application:

A1D series thermal protectors are devices for protecting against overload and over temperature. They are usually used for AC 220v /50Hz one phase motors to protect motor from over temperature caused by unusual state such as overload, blocked up. They are also used for protecting against over temperature & temperature control in lighting appliance, heater, fluorescent ballast, IC etc.

Main features:

Snap action, normal closed, auto reset

Contact rating: 10A/125VAC; 6A/250VAC; 10A/24VDC
