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/ mormal open type, auto reset

Normal closed  type: cutoff at temperature rises; Normal open type: contacts closed (ON) at termprature rises.

Contact rating: 10A/125VAC; 5A/250VAC; 10A/24VDC 
Thermal switch dimension: 15X6.5X3.1mm

Open Temperature: 50C to 155C,  in 5C increasement
