Compressor Motor Protectors
Each compressor incorporates a motor protection device or system. Generally, the
larger the compressor, the more sophisticated the motor protector.
It is essential that an electric motor is protected against conditions that could
otherwise result in damage to the motor or to the electrical supply system. For this
reason, every Kulthorn compressor is supplied with a motor protector, sometimes referred
to as an overload. The more expensive the compressor, the greater is the economic
justification for specifying a motor protector that has the ability to protect over a wider
range of conditions.

  1. External Motor Protectors
    A smaller compressor (such as an AZ, AE or WJ) is fitted with an external motor
    protector. Most commonly, this is a compact, cylindrical device that contains a snapaction bimetallic disc. The protector is mounted in contact with the surface of the
    compressor housing, inside the terminal guard.
    The compressor current passes through the bimetallic disc. The resistance of this disc
    causes the disc temperature to increase as the motor current increases. There is usually
    a small heater, located under the disc and connected in series with the disc itself. This
    heater further raises the temperature of the disc. There is also the impact of the
    compressor shell temperature, and a hot compressor will further increase the disc
    temperature. The temperature of the disc is thus influenced by the combined effects of –
    • the compressor motor current
    • the compressor shell temperature
    When the bimetallic disc reaches a predetermined temperature (often either 105°C or
    120°C) the disc will snap open, and power supply to the compressor will be interrupted.
    The compressor will cool, and at a reduced disc temperature the protector will reset
    and the compressor will restart, or attempt to restart. If the abnormal condition that
    caused the protector to trip in the first place still exists, the compressor is likely to continue
    to cycle on the overload until that condition is corrected.
    There are two situations where a motor protector is expected to operate.
  2. When the compressor is running under extreme conditions.
  3. When the compressor is in a locked rotor condition. This is a situation where the
    compressor cannot start because the voltage is too low, the system pressures are
    outside the range for which the compressor is approved, there is internal damage to
    the compressor, or there is some other reason why the compressor is incapable of
    starting
