KSD301 Thermmostat
Structural featuresFeatures of structure
KSD301Series sudden jump thermostats are small bimetallic thermostats, which belong to the category of temperature relays. Utilizing the principle of instantaneous beating of the disc-shaped bimetallic sheet under the action of temperature, the contact is moved quickly through the action of the mechanism to achieve the purpose of disconnecting or connecting the circuit. Its working temperature is fixed and no adjustment is required; its action is reliable and crisp, with small arcs; its service life is long; and its radio interference is small.
RS-D301 snap action thermostat is small-size bimetal thermostat series with a metal cap, which belongs to thermalrelays’family.The main principle is that one fumction of bimetal discs snap action under the change of sening temperature.The snap action of disc can push the action of the contacts through the inside structure, then caused on of off of the circuitfinally. The main characteristics are the fixation of working temperature, the reliable snap action, less flashover, longer working life and less radio interference.
