Trimax Circuit Protectors
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.
Expansion Type Circuit Protectors
Trimax Expansion Type Circuit Protectors operate on the principle of a load current flowing through an extremely thin, special alloy wire or strip, which is held under tension. Due to its extremely low mass and configuration, the electrical resistance encountered causes it to rapidly expand precisely at its designated trip point, and by doing so, to open a set of contacts. An integral spring mechanism of the same alloy ensures “snap-action” opening of contacts, thereby extending operating life.
Due to the extremely low mass of the current-carrying wire or strip, coupled with the unique thermal expansion characteristics of the alloy used, the Trimax Expansion Type Circuit Protector is insensitive to variations in ambient temperature, and requires no compensation for ambient temperature.
Sockets | Input Receptacle Assemblies
As a complement to our broad range of circuit protectors, Trimax offers a variety of AC power receptacles. These products range from a basic AC socket to printed circuit board mount designs, as well as sockets that integrate a fuse or a manual reset circuit protector built into the assembly.
