KSD307 KSD308 Big Current Bimetal Thermostat 70C 90C 95C 250V 50A 60A for Boiler Water Heaters
The series of KSD307 thermostat that is of double-pole structure falls in the category of manual reset type temperature controller. The product series, safety and reliable, is used in high-duty electric water heater for overheating protection. When the instant snap of bimetal disc occurs at certain temperature, two contacts separate promptly by means of mechanical transition and simultaneously two-phase circuit disconnects in order to completely cut off power supply. Pressing reset lever will restore the power supply.(heavy-duty thermostat)
Technical Requirements of KSD307 Thermostat
1)rated voltage and current: AC250/40A-60A
