7895 Hermetic Motor Protector
Motor Protectors
The basic element in the on-winding motor thermostat is the Klixon® snap-acting disc. The electrical circuit consists of the pin, insulated from the case by the glass-to-metal seal, connected to the stationary contact through the disc to the case. In the 7895 thermostat, the metal case is electrically hot and requires some method of insulation from the motor windings. Several custom configurations of insulation and terminations are available at slight additional cost.
