Klixon® 34HM SERIES

Manufacturer: Klixon®

Hermetically Sealed On-Winding, 3-Phase Motor Protectors

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.

Features & Benefits

  • 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.
Application 3-phase motors from 1 to 6HP
