TPEL thermal fuses in the TH99 HOL series permanently open the circuit when the temperature reaches 99°C, providing one-shot overtemperature protection at one of the highest trip points in the TPEL HOL range. Sold in packs of 2, they are used in transformers, ventilation systems, electric fans, low-power motors, chargers, electronic ballasts, capacitors, and various heating systems.

The HOL (hollow lead) construction suits PCB through-hole mounting and in-line wiring. The fusing-off temperature of 97°C (+2/-3°C) and 71°C holding temperature are suited to high-temperature equipment where the normal operating temperature approaches 70°C before fault conditions trigger the fuse.

Key Features

• Rated functioning temperature (TF): 99°C — opens permanently at this temperature
• Fusing-off temperature: 97°C +2/-3°C
• Holding temperature (TC): 71°C — safe continuous operating temperature
• Maximum temperature limit: 150°C
• Rated voltage: 250V AC
• Rated current: 10A

Product Benefits

• 99°C trip point is one of the highest in the TPEL HOL series, suitable for very hot operating environments
• 71°C holding temperature prevents false tripping in high-temperature enclosures under normal load
• Non-resettable design provides a clear, permanent indication of the overtemperature fault
• 10A current rating covers low-power motors, chargers, ballasts, and capacitor circuits
• 150°C maximum temperature limit gives a 51°C safety margin above the trip point
