H0-2K thermal relay plugged version

The three phase thermobimetal relays are suitable for the protecting of the electrical consumers – especially electric motors – against overcurrent and overheating.

Current ranges [A]

  • 0,2…0,3 ; 0,3…0,45 ; 0,45…0,67 ; 0,67…1,0 ;
  • 1,0…1,5 ; 1,5…2,2 ; 2,2…3,3 ; 3,3…4,9 ; 4,9…7,3 ;
  • 7,3…11,0 ; 11,0…16,5 ; 16,5…25,0 ; 21,5…32,0 ;

Characteristics of H0-2K thermal relay

  • The value of the motor’s rated current should be adjusted by the knob to the arrow
  • The resetting mode (manual or automatic) can be chosen
  • TEST button is suitable for testing  the functional capability
  • The thermal relays have a double slide-system which operates the switch-off mechanism, in case of phase failure, it releases faster
  • The contacting mechanism contains two electrically independent NO and NC contacts.
  • The compensating bimetallic unit ensures the operation on the given wide ambient temperature range ambient temperature
  • In the final technical execution (with adapters) the thermal relay can be connected by wiring to any contactor
  • The device can be plugged directly to lower terminals of DL-K4-…DL-K18 contactors after removing the fixing and connecting elements
  • The thermal (overload) relays refer to requirement of standard EN 60947-4-1.


They may be used in motorstarter, reversing, star-delta and other combinations

Relevant standard: EN 60947-4-1
