Import 17ame+Ptc Self-Hpld Thermal Protector — Buy in Bulk from Supplier in China

The 17AME+PTC Self-hold Thermal Protector from Yangzhou Wuyue Electric Co., Ltd is an assembly combining a 17AME thermal protector with a heating PTC (Positive Temperature Coefficient) element. This unit provides both power cut-off and a self-hold function, which makes it more secure than standard auto-reset protectors for motor-driven appliances. Its operating temperature tolerance is ±3°C or ±5°C, and it is designed to protect against both over-heat and over-current conditions in applications like vacuum cleaners and power tools.

The working principle involves the protector and PTC connected in parallel, then in series with the motor. Under normal operation, current flows through the low-resistance protector. If the motor overheats, causing ambient temperature to exceed the set point, the protector opens. Current then diverts to the high-resistance PTC, which limits motor current to a negligible level and generates its own heat to keep the protector open until power is unplugged. The casing is sealed to prevent contamination from insulating varnishes.

This protector is specified for use in motorized equipment such as blenders, grass cutters, snowplows, and other electrical tools where a stalled motor presents a fire risk. The self-hold feature ensures the device remains off after a fault, requiring a manual power cycle to reset, which is a critical safety requirement for many tool standards. Buyers should verify the exact temperature code and the UL&CUL certification (E258612) listed for the base 17AME model applies to their chosen configuration.

Yangzhou Wuyue Electric Co., Ltd is a manufacturer of thermal protection components located in Yangzhou, Jiangsu, China. The supplier's profile is listed with a 'harbor' trust tier, but specific response rate and time data are not provided, indicating that initial inquiry response times may vary. The company's address is in the Software Information Industrial Park in Yangzhou.

The product listing for the 17AME+PTC protector includes a detailed working principle and application examples, demonstrating technical familiarity with motor protection. It references a specific UL&CUL certification number (E258612) for the base 17AME protector, but does not explicitly confirm this certification covers the assembled 17AME+PTC unit. The listing does not provide information on the company's production scale, years in operation, or major clients.
