JDB-1 32-80A Electronic Overload Relay 4 LEDs For Status Indication
Description
JDB-1 32-80A Electronic Overload Relay is used for protect the device of overload(overcurrent),phase loss and phase unbalance from Pumps,Fans,Motors etc.
Because of the compactness size they are easy to use such as the elevators and lifts for monitoring the phase to ensure equipment working safely
Note: the contact is SCR output,it can't connect with DC contactor.
Features
(1) Integrative structure
(2) Three-phase monitoring of overload, phase loss, phase unbalance
(3) Powered by the measuring circuit
(4) 1 NC SCR output contact
(5) 4 LEDs for status indication
