TPEL thermal fuses in the TH94 HOL series permanently open the circuit when the temperature reaches 94°C, providing irreversible overtemperature protection. Sold in packs of 5, 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 is suitable for PCB through-hole mounting and in-line wiring. The tight fusing-off band (92°C ±2°C) and 66°C holding temperature suit high-temperature operating environments, while the 150°C maximum temperature limit preserves a wide safety margin above the trip point.

Key Features

• Rated functioning temperature (TF): 94°C — opens permanently at this temperature
• Fusing-off temperature: 92°C ±2°C
• Holding temperature (TC): 66°C — safe continuous operating temperature
• Maximum temperature limit: 150°C
• Rated voltage: 250V AC
• Rated current: 10A

Product Benefits

• 94°C trip point is suitable for high-temperature enclosures where lower-rated fuses would trip prematurely
• Tight fusing-off band (92°C ±2°C) provides precise, consistent activation close to the rated temperature
• Non-resettable design gives a permanent, verifiable record of the overtemperature fault event
• 10A rating handles motors, chargers, and ballast loads commonly found in heating and ventilation equipment
• Pack of 5 supports immediate repair and production batch requirements
