Bimetallic ThermostatCS-1, CR-1
High-Current Capacity Thermostat
Designed to have larger electric ratings than CS-7. It is designed to be used at up to 35A / 250V AC. It can be used to control large appliances and prevent excessive temperature rise in them.The CR-1 is a high-current capacity, manual reset type that will not automatically reset at room temperature once it has functioned, same as the CR-7.
