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

2)open temperature range: 50-150C(Normally closed/manual reset)

3)electrical strength

4)Insulation resistance: under normal≥100MΩ

5)contact resistance: ≤50M Ω

6)shell material is bakelite shell

Working Principle of 60A Big Current KSD307 KSD308 Thermostat

Bipolar jump thermostat is a bimetal thermostat with a shell. The use of disc-type bimetallic film in the role of the moment under the principle of instantaneous beating, through the role of mechanical structure, so that the two groups of contacts quickly action to achieve the same time to disconnect or turn on the purpose of bipolar circuit.
