1 ELECTRONIC MOTOR PROTECTION RELAYS

2 ELECTRONIC MOTOR PROTECTION RELAYS Electronic Multifuctional Motor Protection Relays are designed to monitor two/three phase motor currents by integral/external current transformers and processing it further through a Electronic Circuitry and delivering its control signal to the output part to interrupt power incase of abnormal conditions of motor. SALIENT FEATURES Multifunctional Protections in Single Unit Adjustable and Tripping time Low Power Consumption High Accuracy Ammeter Function through LED/Digital display DIN Rail/Panel Mounting Test Function Ambient Insensitive Selectable /Inverse Time Characteristics For currents above 60A external CT should be used Trip Indication through LED/Digital display It can provide various protections for motors like Overload, Phase Loss, Locked Rotor, Phase Unbalance, Undercurrent, Phase Reversal, Ground Fault etc. The Over Relays are available from 0.5 to 60 Amp., extendable up to 960 Amp. using external CTs. Applications include Pumps, HVAC, Conveyor System, Machinery and other single or three Phase equipment. Model: BOCR SS Time Type Over 60 Start DTime Trip OTime 0.5 ~ 6A 3.0 ~ 30A 5.0 ~ 60A Ext.
