BW-S series thermal overload relay / motor thermal protection switch is a newly developed one in Changsheng. It employs stainless steel casing. Relying on the temperature sensing of the bimetal and the current thermal effect, BW-S enables the condition of the bimetal to change swiftly, and then makes the circuit open. BW-S series thermal protection device is mainly applied in air conditioner motor, washing machine motor, pump motor, battery pack, heater, lamp, and ballast, etc.

Difference between BW-T and BW-S
BW-T and BW-S series thermal overload relay is collectively called BW series. The difference is that the casing of BW-T is made from stainless steel, and that of BW-S is made from plastic.

Features
1. The enclosure of BW-S series thermostat protector is made from plastic (doesn't need to be used with insulating sleeve), making its volume smaller than that of BW-T
2. Rated capacity of contact: 10A/24V DC, 10A/125V AC, 6A/250VAC
3. Contact resistance: ≤100mΩ (under room temperature)
4. Tensile strength of wire: putting the lead wire under a 50N axial pressure for 1min, and the wire shouldn't get broken or fall off from the motor thermal protection switch
