Manufactured in a fully automated process, these fire detection fuses are particularly economical for domestic applications in mechanical ventilation, extractor hoods.

They are also externally coated with an alloy protecting them from corrosion.

Material: Brass (possible realization in red copper if shorter response times are required).

Surface Protection: Eutectic alloy

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 the previous ones) 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 printed 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 apparatuses retain their aptitude for the function, in the response times specified by the standard.
