Characteristics
With pure design temperature, current effect is small
Epoxy sealing to ensure that the vacuum varnished.
Closed structure can make components from dust or impurity
pollution and damage to the external force.
Preset calibration temperature ; not adjustable in the field.
Case electrically alive; insulating sleeving is available.
Structure and Working Principle
This product is produced according to the thermal bimetal material
heated bending force characteristics, the butterfly double metal components for special treatment, with the increase of temperature,
butterfly storing energy device, when the temperature reaches
thermal protector rated breaking temperature, the effects of
butterfly element force moment reverse action, disconnect contact,
to cut off the circuit of protected, so as to achieve protection
function;When the temperature drops to the automatic reset
temperature of the thermal protector, the contact closes the
connection circuit and the power is restored.When the current of
the protected body exceeds the rated current, the butterfly element
generates heat energy due to the current. When the temperature of
the thermal protector is reached, the acting force generated by the
butterfly element will reverse in an instant and cut off the
circuit, thus achieving the protection function.
Applications
Pump, high power motor
Heating tube
Electric tool, battery packs
Higher Current BRI Series Thermal Protector
