TPEL thermal fuses in the TH72 HOL series permanently open the circuit when the temperature reaches 72°C, protecting equipment from overheating damage. Sold in packs of 5, they are suitable for 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 68°C (+2/-3°C) and holding temperature of 45°C are calibrated for equipment where heat builds gradually under normal load.

Key Features

• Rated functioning temperature (TF): 72°C — opens permanently at this temperature
• Fusing-off temperature: 68°C +2/-3°C
• Holding temperature (TC): 45°C — safe continuous operating temperature
• Maximum temperature limit: 150°C
• Rated voltage: 250V AC
• Rated current: 10A

Product Benefits

• 72°C trip point protects equipment that operates at moderate temperatures under normal conditions
• Non-resettable design ensures permanent circuit isolation on overtemperature fault
• 10A current capacity covers the load of most low-power electrical equipment
• Holding temperature of 45°C prevents nuisance tripping in equipment with normal warm-up cycles
• Pack of 5 provides spares for maintenance and production use
