Wired thermal fuses, for insertion into 8.5 mm I.D. pockets
Protection against overheating of equipment and heating elements
|Rated functioning temperature (°C) Tf|
|Holding temperature (°C) Th|
|Maximum temperature (°C) Tm|
Applications: protection against overheating of equipment and heating elements
Fusible pellet: organic compound
Mechanism: movable pellet actuated of a spring released by the fusion of the pellet
Protection: with electrical insulation silicone boot, dia. 8mm
Nominal current rating: 16A 250V
The nominal current rating is the maximum current the fuse can carry without opening or deteriorate when subjected to a temperature known as the “holding temperature” (Th) for a limited time
Holding temperature (Th): the fuse must not open or be destroyed when subjected to a temperature equal to Th-6 °C for a period of 168 hours under nominal voltage and current
Rated functioning temperature (Tf): It is the opening temperature of the fuse in a calibration oven, when subjected to a current less than 10 mA, when temperature rises at a speed of 0.5 to 1 °C / min. The opening temperature must not be lower than Tf-10
°C or above Tf under these conditions. This is the operating temperature Tf which is printed on the fuse and the protective sheath external of the leads.
Maximum temperature (Tm): it is the maximum temperature withstood by the fuse after opening without losing its insulating and mechanical properties.
Insulation voltage between open contacts: ≥ 500V
Insulation resistance between open contacts: ≥ 0.2 MΩ @ 500V
Lead lengths: 500 mm.
Leads: FEP 300V primary insulation, 1 mm² gauge (AWG18), in a polyolefin sheath.
