Automatic Reset Thermal Overload Protector

Automatic Reset Thermal Overload Protector is a heat/load protection device whose bimetal can return to service after the matched reset condition is reached. It is not limited to motors: the supplied application list also covers power supplies, generators, transformers, test instruments, extension cords, power tools, UPS products, exercise equipment and food-processing machinery.

The nameplate reference attached to Automatic Reset Thermal Overload Protector is: 125VAC / 250VAC / 32VDC; AC frequency 50-60Hz; dielectric test 1500VAC for 60 seconds; make/break capability 3 times the rated current; laboratory ambient 25°C ±3°C. No single reset point or timing curve is defined in the source. Those characteristics have to be established from the equipment current, fault load, heat build-up at the installation point and surrounding ventilation.

Samples can be developed from equipment drawings, a prototype or measured operating conditions. Gan'en Electronics makes the overload bimetal and assembles the protector; stated monthly capacity is 4 million units. The purchasing reference is 10,000 pcs MOQ, free regular samples excluding courier charges, about 7 days for regular production and about 15 days for customized work.

For the final Automatic Reset Thermal Overload Protector version, the sample test can combine physical installation, circuit continuity and operation under the customer's own load pattern. During lot production, acceptance evidence is collected at raw-material entry, workshop stages, completed-unit review and shipment release, followed by 100% checking at pack-out. Buyers may appoint an outside inspector. Images or video can document the order, while carton and lot records provide the reference if transport-related questions arise.
