How Saftty Thermal Protectors Can Help Your Transformers?

Transformers are an integral part of any electrical system and they can be found in homes, businesses, schools, and hospitals. Transformers convert the incoming electricity from high voltage to low voltage so that it can be used in a particular building or area. As with any electrical component, they require regular maintenance – typically this would involve the electrician checking things like the oil levels, connections, and insulation. However, there is one detail that you might not have considered: Saftty thermal protectors.

How does Saftty thermal protectors work?

When a transformer is overloaded, the windings can overheat and cause damage to the insulation. To prevent this, most transformers are equipped with thermal protectors.

Saftty thermal protectors are devices that monitor the transformer’s winding temperature and automatically disconnect the transformer from the power supply if the temperature gets too high. The thermal protector will then reset itself once the winding has cooled down enough.

Thermal protectors are usually installed in the transformer’s secondary winding, as this is where the majority of heating occurs. However, some larger transformers may have thermal protectors in both the primary and secondary windings.

Saftty SYT6 Series Thermal Protector Help Transformers

The materials used in Saftty SYT6 Series Thermal Protector are integrated global supply chain resources, so the thermal protector has good consistency and stable performance. Here are the benefits:

  • Good sealed.
  • Small in size, normally closed thermal switch ST06 can be embedded inside the coil.
  • The metal case of normally closed thermal switch ST06 can bear up to 50KG coil shaping pressure and has high thermal conductivity and is temperature-sensitive.
  • Pure temperature action type products, bimetal-disc without current and heat effect, accurate temperature control.


If you are looking for ways to improve the efficiency of your transformers, Saftty thermal protectors can be a great option. By preventing overheating, they can help extend the life of your transformer and improve its performance. Saftty thermal protectors come in a variety of shapes and sizes, so it is important to choose one that is suited for your particular transformer. With so many benefits, there is no reason not to try a thermal protector for your next project.
