Our connectors are made of Polypropylene (which is a flame retardant material) according to the supplier this material can hold up top +-165C.
Although I will not recommend more than room temperature + 40C.
Keep in mind cables will not stand such temperature anyway as they normally rated between 75C to 90C
Some of the key features are:
- Cable Connectors
- Single or double screw
- Clear insulated
- Suits up to 2 x 6mm² cables
