Self-hold Thermal Protector 50- 170 for thermal protection, manual reset
Description
The Self-Hold 17AM-D+PTC is a thermal Protector/PTC Heater combination. The PTC Heater is electrically located across the contacts of the protector. When the protector contacts are open, the heater is in series with the load. The heater then maintains the temperature sensitive bimetal of the protector in an open state. To reset the Self-Hold 17AM-D+PTC, power must be removed for sufficient time to allow the Self-Hold 17AM-D+PTC to cool to below the protector’s reset point.
In a fault condition, the 17AM-D+PTC opens the electrical circuit and an integrated heat source prevents the thermal protector from reclosing until the power source is removed and the unit is allowed to cool the thermal protector then resets allowing continued operation.
