New Thermal Fuse from Foremost has the Highest holding and Open Temperature on the Market

Foremost Electronics, the Essex based specialist distributor of electromechanical components, announces the availability of Therm-O-Disc’s new G4 257C Microtemp® Thermal Fuse which offers the highest holding temperature and highest open temperature available in the market.

MICROTEMP® thermal fuses from Therm-O-Disc® represent the global standard in thermal fuses.  MICROTEMP® thermal fuses offer an accurate, reliable solution to the need for upper limit temperature protection against overheating by interrupting an electrical circuit when operating temperatures exceed the rated temperature of the thermal fuse.  The G4-series is rated for continuous operating currents up to 10 amps at 250 VAC.

The global agency recognition of the G4-series enables use in a wide range of applications including major and portable appliances including high speed blenders as well as personal care products such as high power irons, steamers and hair straighteners.

The hold Temperature (Th) of the MICROTEMP G4 257C has been increased to 220ºC to ensure applications with higher normal ambient temperature requirements will have added assurance of maintained operation for a minimum period of 168 hours without opening, as tested per IEC 60691.

Other key features include fully safety agency approved to UL, VDE, CSA and CCC and evaluation in laboratory conditions to maintain continuity for 1,000 hours at continuous thermal fuse body temperature of 220ºC

Full application notes are available for the Microtemp® to ensure users can determine the suitability of the control device for their specific applications, including the level of reliability required

Alan Cook, Managing Director of Foremost Electronics, comments, “MICROTEMP® thermal fuses from Therm-O-Disc are available in a variety of standard and custom configurations, providing reliable one-shot over-temperature protection for a wide variety of applications.  The new G4 series offers a safe and reliable safety cut-out for the growing number of high power and high speed products being introduced almost daily.”
