Import Aupo Thermal Cutoff 73~240degree Pellet Type — Buy in Bulk from Supplier in Hong Kong

The Aupo thermal cutoff 73~240degree pellet type is a pellet-type thermal fuse with a rated current of 10A and voltage of 250V, designed to interrupt circuits when ambient temperature exceeds the calibrated threshold. The operating temperature range spans 73 degrees C to 240 degrees C, with UL, VDE, CCC and PSE safety marks. Construction is compact and epoxy-sealed to protect the pellet mechanism from moisture and mechanical disturbance.

Pellet-type thermal cutoffs typically employ a fusible alloy pellet held under spring pressure by a metal casing; at the rated temperature, the pellet melts and the spring-loaded contact separates permanently. Epoxy sealing provides ingress protection to IP40 or better, though this is not formally rated in the source. The 10A/250V rating suits applications in switch-mode power supplies, transformers, motor windings, and battery chargers where over-temperature protection is mandatory under IEC 60691 or equivalent national standards.

Target buyers include manufacturers of coil-wound products, network and telecommunications equipment, household appliances, audio-video equipment, and personal electronics. The thermal sensitivity and stable functioning characteristics cited suggest application in products with limited ventilation or thermal runaway risk. Confirm with Wealth Tower Electric Ltd. whether reel packaging or ammo pack options are available, and whether custom temperature set points within the 73-240 degrees C range are offered.

Wealth Tower Electric Ltd. is registered at Winful Centre, 30 Shing Yip Street, Kwun Tong, Kowloon, Hong Kong. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00% and zero recorded average response hours. This indicates no platform-mediated communication history; buyers should initiate direct contact and assess responsiveness before committing to orders. The Hong Kong address suggests a trading office or headquarters function rather than manufacturing, though this is not confirmed in the source data.

The company profile does not disclose factory location, year of establishment, annual turnover, number of employees, or specific manufacturing certifications such as ISO 9001. No client list, production capacity, or in-house testing capability is stated. The Aupo product name may indicate a brand or manufacturing partnership; buyers should clarify whether Wealth Tower Electric Ltd. is the brand owner, licensed manufacturer, or distributor, and request evidence of mark authorization for UL, VDE, CCC and PSE certifications directly from the supplier.
