The three phase thermobimetal relays are suitable for the protecting of the electrical consumers – especially electric motors – against overcurrent and overheating.
Current ranges
Characteristics of MH 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 ont he given wide ambient, temperature
The device can be plugged directly to lower terminals of MK 2 and MK 4 contactors.
The thermal (overload) relays refer to requirement of standard EN 60947-4-1.
