KST series of small-sized thermostat and bimetallic thermostat dedicated for switchgears 0℃~60℃

Description

General

KST series of small-sized temperature controller is mainly used to protect the electrical equipments against freezing in low temperature environments. It can automatically start fans or heaters and adjust temperature and humidity of the surrounding according to on-site situation. The contacts will output action indication signals, when ambient temperature is higher than pre- set temperature, the contact of controller will flip so to protect the equipments from being damaged. The thermostat is a smart controller which makes it to suit to the more complicated environment and protect the equipments more effectively.
