T63I  thermal relay 21…75 A
for DL-K22-, DL-K30-, DL-K37- contactors

T 63I thermal relay

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

Current ranges [A]

  • 21…30 ; 30…40 ; 43…63 ; 52…75 ;

Characteristics of T63I 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 chose with blue knob
  • TEST button (red) 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
  • The relay can be plugged directly to lower terminals of DL-K-22-11, DL-K-30-11, DL-K-37-11 contactors
  • The thermal (overload) relays refer to requirement of standard EN 60947-4-1.

Using

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

Relevant standard: EN 60947-4-1
