H0-2K thermal relay to DLK-4 ... DLK-18 contactors
The three phase thermobimetall relays are suitable for the protecting of the electrical
consumers - especially electric motors - against overcurrent and overheating.
Characteristics of H0-2K thermal relay:
The compensating bimetallic unit ensures the operation irrespectively the actual ambient temperature
(within the given wide temperature-range).
The resetting mode (manual or automatic) can be chosen.
The thermal relays have a double slide-system which operates the switch-off mechanism, in case of
phase failure. It releases faster: (by standard within 2 hours at 15 % overload, but in practice after some minuts).
TEST button is suitable for verification of the functional capability.
The thermal (overload) relays refer to requirement of standard EN 60947-4-1.
The contacting mechanism contains two electrically independent NO and NC contacts.
They may be used in motorstarter, reversing, star-delta and other combinations.
In the final technical execution (with adapters) the thermal relay can
be connected by wirning to any contactor.
The device can be plugged directly to lower terminals of
DLK-4-...DLK-18 contactors after removing the fixing yn connecting
