sensata.com Page 1 Copyright © 2025 Sensata Technologies, Inc. 15HM SERIES | MOTOR PROTECTORS Hermetically Sealed Single Phase On Winding Protection SPECIFICATIONS Features and Benefits Line Break Operation

  • High Reliability – 2 contact ratings
  • Optional start winding protection
  • Compact and rugged construction
  • Meet rotary compressor high side pressure requirements
  • Application range – 1 to 5 HP The 15HM family of motor protectors can be applied to unitary air conditioning and heat pump compressors ranging from 1 to 5 HP. They may also be used in commercial motors which must function in destructive or corrosive environments. Its compact and rugged design make it resistant to mechanical shock and suitable for installation directly on motor windings. Klixon® 15HM motor protectors are line break automatic reset controls which are wired in series with and mounted on the motor windings. These protectors track winding temperatures and respond to changes in line current to afford protection against the wide variety of overload conditions listed below:
  • Running overload • High/low voltage locked rotor
  • Loss of refrigerant charge • Shorted capacitor
  • High discharge temperature • High Voltage Light Load
  • Welded Start Relay • Blocked Condenser Fan Open Temperature 90ºC - 165°C Tolerance ±5ºC Open, ±9ºC Close Series Start Winding Line Voltage Locked Rotor Current HP Range 300 13XX-15XX 17XX-25XX Yes No 230V *100 Amp *1 - 3 1/2
