Import 17am/17amc/7am+Ptc Thermal Switch — Buy in Bulk from Supplier in China

The 17AM/17AMC/7AM+PTC is a thermal switch series designed for temperature and current protection in electrical motors and appliances. It combines a bimetallic disc (for current sensing) with a PTC (Positive Temperature Coefficient) thermistor (for temperature sensing) in a single compact housing. This dual-function design allows it to respond to both over-current and over-temperature conditions. Dongguan Kain Electronic Sci&Tech.Co.Ltd, based in Guangdong, China, supplies these switches as components for industrial and consumer product assembly.

These switches are commonly specified with a rated voltage of 250V AC and a current capacity that varies with the model, often in the range of 5A to 16A. The operating temperature trip point is typically set between 60°C and 180°C, depending on the specific model number. The construction is robust, with a metal or ceramic housing, and they are designed for direct mounting on motor windings or within appliance casings. The supplier's description highlights their quick action and high sensitivity, which are critical for preventing damage in motors, transformers, and power tools.

Buyers of these thermal switches include manufacturers of electric motors, HVAC compressors, power supply units, and industrial machinery. They are a standard safety component in applications where overheating poses a fire or failure risk. When sourcing, it is essential to specify the exact model number (17AM, 17AMC, or 7AM+PTC) and the required temperature rating. The supplier offers flexible MOQ options, and trade terms such as FOB or CIF can be arranged for international shipments from China.

Dongguan Kain Electronic Sci&Tech.Co.Ltd is a manufacturer and supplier located in the Tiantou Industrial Zone, Hengli Town, Dongguan, Guangdong, China. The company specializes in electronic components, with a focus on thermal protection devices like the 17AM series switches. Their platform profile indicates a 'harbor' trust tier and lists them as an 'imported' supplier, though their response rate is currently at 0%.

The supplier's listing emphasizes the product's features, such as robust construction and compatibility with various systems, but does not provide detailed company background, factory size, or specific quality management certifications. The address places them in a major manufacturing hub for electronics in China. Buyers should contact the supplier directly using the provided address to request company documentation, discuss minimum order quantities, and verify their production capabilities and lead times for the specific thermal switch models needed.
