Self-Hold Manual Reset 17AM Thermal Protector For Vacuum Cleaner
Applications:
Description:
Self-Hold 17AM-D+PTC thermal protector combines the protection of a 17AM-D with a self-holding feature. Designed to prevent overheating in motors, the Self-Hold 17AM offers the best attributes of one shot protectors and auto reset protectors in a single package. The Self-Hold 17AM-D, once activated in a fault condition, maintains its open state until power is removed. No reset button remove power and the device will cool and reset. This inherent design feature adds an extra level of security over automatic reset devices of any type. It is the reliable, cost effective solution for numerous applications.
How the Self-Hold 17AM-D functions?
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, power must be removed for sufficient time to allow the Self-Hold 17AM-D to cool to below the protector’s reset point.
