17AM Self-Hold bimetal switch with PTC Heater for thermal Protector
17AMH.pdf
Product Description
When the temperature of the disc reaches a predetermined
calibration point, the disc snaps open the contacts, thus breaking
the current path. When the equipment returns to a normal operating
range, the 17AM resets (close circuit) automatically. 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, power must be removed for sufficient time to allow
the Self-Hold 17AM to cool to below the protector’s reset point.
Self-Hold 17AM performance is dependent upon the applied current as
well as temperature. Different Bi-metals are incorporated to
achieve various performance characteristics. In applications where
temperature rise is less than 2°C per second, use low-resistance
ratings. High-resistance Bi-Metal is recommended for applications
with 2°- 5°C per second rates of temperature rise.
