KSD303/KSD308 series thermostat, is a fully enclosed bimetallic sheet contact temperature relay, according to the principle of hot expansion and cold shrinking to bend the metal sheet, so as to achieve a pre-set temperature range of rapid jump and switch on, the electrical appliances play a safety protection role, its disconnect temperature and re-temperature can be made according to customer needs.
Note:
1) When using contact-sensing temperature mounting, the metal cover surface should be attached to the mounting surface of the accused apparatus.
2) Do not deform the cover face when installing, so as not to affect performance.
3) To prevent leakage, do not allow liquid to seep into the thermostat, so as not to affect electrical reliability.
4) This product is bipolar wiring, when used in accordance with the marking symbol, correct wiring.
5) Products should be less than 90% relative humidity, ambient temperature of less than 40 degrees C ventilation, clean, dry, non-corrosive gas storage.
