These fusible links have a medium response time, between 3 minutes and 3 minutes 10 seconds, for a temperature rise rate of 20°C/min from 25°C and their thickness of
metal gives them sufficient strength for their use in multiplied mechanisms supporting a maximum load of 300DaN.
The holes have a lip to improve their resistance to mechanical break at 25°C by avoiding the tearing of the metal.
Material: Brass
Surface Protection: No special surface protection.
ROHS compliance: These fusible links are available in two versions.
- Non-ROHS compliant, using traditional alloys containing lead and cadmium, for temperatures 68°C (155°F); 72°C (162°F); 96°C (205°F); 103°C (218°F); 120°C (248°F).
- ROHS compliant, using ternary alloys based on bismuth, tin and indium, (the high cost of indium makes these models 2 to 3 times more expensive than non-Rohs types) for temperatures 60°C (140°F); 72°C (162°F); 79°C (174°F); 109°C (228°F); 117°C (242°F).
Identification: Model, temperature in °C and date of manufacture are stamped on each fusible link.
Tests:
- Mechanical resistance at ambient temperature: 100% in production.
- Trip temperature under static load: by statistical sampling.
- Trip time in temperature rise under load according to ISO 10294-4: by statistical sampling.
- Holding load 1h at 60°C or 90°C: compliant and verified by statistical sampling in production (Test according to ISO 10294-4).
- Triggering under minimum load: compliant and verified by statistical sampling in production (Test according to UL33)
Salt spray resistance: According to ISO9227-2012, subjected to a mist formed of 20% by weight of sodium chloride in distilled water, at 35°C for 5 days (120h), the
fusible links retain their aptitude for the function, in the response times specified by the standard.
