Notices

NOTICE 1: As you may or may not already know. NTE is officially out of business and we are unable to order parts from them ever again.

However, we were able to locate the company that NTE used to make these Thermal Cutoffs (All NTE did was relabel product and resell it). This means that you may order the NTE part, but we may ship different part numbers that are the original parts that match the NTE specifications. Certificates Of Conformity are available from us, upon request.

NOTICE 2: These no longer come with the un-insulated crimp butt connectors that NTE used to include with them. If you need them, we recommend either ordering SR-BUT-2N. If you have a special need for them, you can always email us for more information and we are always here to help.
