45~100 Dan Load Direct Handling of Heavy Loads Fire Detection Eutectic Alloys Fusible Links

Product Description

Eutectic alloys fusible links, for direct handling of heavy loads These fusible links have a response time near the highest limit requested by standard (whose threshold is 4 minutes), between 3 minutes 30 seconds and 3 minutes 50 seconds, for a temperature rise rate of 20°C/min from 25°C. Their 1.5mm metal thickness and their soldering surface make it possible to withstand directly and without multiplying mechanism the loads encountered in the opening or closing mechanisms of fire doors and shutters. Material: Brass (Copper possible) 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.

Maximum permanent load depends on alloy composition and ambient temperature on 72°C fusible links. Values are given for guidance only, and for a 72°C non ROHS eutectic alloy. Alloys with temperatures below 72°C and those that are ROHS compliant, generally have a high proportion of Indium, which greatly reduces the mechanical strength. ** Values measured in our own testing equipment. Testing conditions and equipment comply with ISO10294-4 and ISO DIS 21925-1 2017, fig. C1 Main references (Non-ROHS)
