T63I thermal relay to
|
The three phase thermobimetall relays are suitable for the protecting of the electrical consumers - especially electric motors - against overcurrent and overheating. Characteristics of T 63I 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. The T 63I thermal relays can be plugged directly to the lower therminals of the DLK-22-11, DLK-30-11 and DLK-37-11 contactors, they cannot mounted independently to a plate or rail. |
