Product Description

RS03 thermal Protector / RS03 thermostat / RS03 temperature protector

1. RS-03 thermal protector's Principle and structure

RS-03 snap action thermostat is small-size bimetal thermostat series with a metal cap, which belongs to thermal relays 'family. The main principle is that one function of bimetal discs snap action under the change of sensing temperature. The snap action of disc can push the action of the contacts through the inside structure, then caused on of off of the circuit finally. The main characteristics are the fixation of working temperature, the reliable snap action, less flashover, longer working life and less radio interference.
