Thermal Protector, BR-B6D Series
BR-B6D thermal protector is a kind of temperature limit switch working to prevent motor or other electrical devices from overheating. It is rather sensitive to temperature change. When there is an accident in a circuit, the high temperature will lead the bimetal to open rapidly and thus cutting the circuit off. The switch will close automatically after the device has cooled down to the allowable temperature. BR-B6D thermal switch is applicable in various small motors, battery, charger, and other electric appliances.
BR-B6D thermal protector is of short tripping time and reliable performance. Upon clients’ request, we can equip the circuit breaker with the required length of wires. Besides, all of our thermal protection devices have passed TUV, UL, and CQC certificates. Our raw materials are in accordance with the environmental requirements of RoHS and REACH.
