Our team of engineers at Calco Electric provide the best quality in thermal protectors. We also offer the best pricing and customer service for our products. No matter your industry or your needs, we have the training and the experience to help.

Our products are used in a variety of industries, including automotive, food service, compressors, A/C motors and transformers, medical, and more.

No Overheating With Thermal Protectors

Thermal protectors are specifically made for motors. When the motor’s heat rises too high, the thermal protector turns off electricity. This stops the motor from overheating and catching on fire.

Thermal protectors are placed internally inside the motor. The elements include two different kinds of metal, like a bimetal disc, to disjoint the contact from the electricity. This feature can be individualized according to the temperature, size, and metals needed.

Choose From a Variety of Thermal Protectors

We create thermal protectors in brass, SS 316, CS, Hastelloys, and Titanium Monel materials. Because we start with materials known for their durability and accuracy, our end products are outstanding.

We give our customers a variety of options, including socket weld, threaded, tapered, flanged, and straight. Each detail is included to make the protectors more efficient.

Our thermal protectors are made with one piece construction. If you want, we can run 100% factory tests for NACE certification. Our elements have heat code traceability, 28” Insertion length, and ½” NPT/NPSM instrument connection.
