Hermetic motor protector |
摘要 |
A thermally responsive motor protector device particularly adapted for protecting a small electrical motor against both overcurrent and overtemperature conditions in an environment requiring hermetic sealing of the protector has a structure which provides the device with the desired hermetic seal and with a very small thermal mass for achieving the desired speed of response to overcurrent and overtemperature conditions in a small motor while also permitting mass production and automatic calibration of the device at low cost and inexpensive installation of the device without risk of loss of calibration.
