    Hermetically Sealed On-Winding, 3-Phase Motor Protectors

      • Protect WYE (Star) wound 3-phase motors from 1 to 6HP.
      • Used in refrigeration compressors, submersible pumps and other restrictive environments.
      • In-line protection in a small, rugged, welded construction.
      • Low profile shape allows for close coupling to motor windings.
      • Hermetic reliability designed for leakage rates less than 1 x 10-9 cc per second of air with 1 atmosphere pressure differential.
      • Klixon® snap-action discs assure positive make and break action and controlled temperature differential.
      • Designed for low and high side pressure applications.

    Description

    This protector is designed to protect 3-phase refrigeration and air conditioning compressor motors from excessive winding temperature; however, applications may be made to any WYE wound 3-phase motors where environmental conditions require a hermetic seal. The low profile permits the device to be installed directly on motor windings for closely coupled temperature monitoring, thus enhancing over-temperature protection against loss of refrigeration charge, low voltage locked rotor, and secondary single-phasing (loss of phase).
    Current ratings are based on life test data which has demonstrated high reliability at 5K cycles (standard series) and 2K cycles (high capacity series) at 0.7 power factor on Sensata life test boards.
    These capacities are intended as a guide for application work.

    Line Break Operation

    Klixon® 34HM motor protectors are line break automatic reset controls which are wired in series with the motor windings. These protectors are designed to track winding temperatures and to respond to changes in line current. When properly applied, the 34HM can provide protection against motor overheating in a wide range of situations. Check out datasheet for further infomations.
