Specification of Overload Relay Schneider LRD 08 2.5 - 4A
Overload AC, LRD08 Schneider, JUAL OVERLOAD AC RELAY LRD08 SCHNEIDER
Overload Relay Schneider LRD08 is switching equipment that is sensitive to temperature and to open or close the contactor when the temperature that occurs outside the specified limits or electrical control equipment which serves to disconnect the electrical network in case of overload.
Safety is more load or overload igunakan on the installation of an electric motor load is TOR.Jika current through a conductor leading electric motor exceeds the capacity or setting TOR, the TOR drop or disconnected so rangkain leading listrk motors disconnected.
TOR is connected with the contactor main contacts (for a particular series of magnetic contactor) is the main contact .Rotasi 2,4,6 before weights or electric motor.
Some causes of overload:
-Beban Mechanic on the electric motor is too big
-Arus Start too big and too old nominal rotation is reached or the electric motor braking
-present A short circuit in the electric motor between the phase by phase, or between fas with body
-Motor Electricity works only with Duaa phase or the opening of one phase of a three-phase electric motor.
The working principle of thermal load by atu temperature heat generated by current flowing through the heating elements from overheating bimetal.Jika then one bimetal curved metal and moving the mechanical contact of electrical circuit breakers.
