Bi-Metallic Circuit Protectors
Trimax bi-metallic circuit protectors operate on the principle of a load current flowing through a bi-metal strip. The electrical resistance encountered causes the strip to heat up, bend, and by doing so, to open a set of contacts.
To ensure rapid opening of the circuit protector contacts, Trimax incorporates a "snap-action" feature as part of the bi-metal strip design configuration. Select Trimax Series Circuit Protectors supplement this feature with a spring mechanism to open the contacts more rapidly to reduce arcing, thereby extending operating life.
Bi-metallic circuit protectors inherently are thermal sensors and as such are affected by ambient temperature. More »
