Product overview

  • Thermal fuse
  • Will protect equipment from excessive temperature rises
  • Not resettable and must be replaced if ‘blown’
  • Never solder directly to the wire leads

A thermal fuse which will protect equipment from excessive temperature rises. It's not resettable and must be replaced if ‘blown’. NOTE: when installing any of these devices, never solder directly to the wire leads – you must use screw terminals, terminal blocks or crimped on connectors.

Rated 3 out of 5 by from I really wanted a resetable fuse but this one was more available for now Price was acceptable but the only one in stock was 25 miles away, fortunately I was able to collect it during my trip for other reasons I also had to compromise with the value I was looking for closer to 70C really

Hi Maplin tech -- I'm replacing a 157C fuse.  Should I go for the lower or higher value - 128C or 192C? Would the lower blow too easily and could the higher potentially cause damage?  Thanks in advance -- Rod

I’m sorry but we do not give advice on any kind of project for liability reasons, If you are unsure of what you are doing with this I can only recommend you get advice from an electrician, we are not qualified electricians so are not able to provide design help, We can only give technical specifications for the items on our site.

Hi, are these fuses for temperatures traveling through them or enviroment temperatures or both?
Asked by: Michael
These are for both, once the temperature reaches the rated temperature, the fuse blows.
