FSTB KSD306 Big Current 250V 16A Bimetal Switch oil heater thermal electric frying oil heaters oven heater pan thermostat
The series of KSD306-B that is of double-pole structure falls in the category of manual reset type high current bimetal thermostat. 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)
