The NewElec EC series of electronic motor protection relays will monitor the insulation integrity of protected motor windings and feeder cable cores to earth while the motor is standing. The main contactor is prevented from closing the circuit in which the insulation level to earth is below the permissible level. The selected Lock-out relay model determines the minimum value of insulation level.

A comprehensive low voltage electronic motor protection relay encompassing new and unique features. Designed for conveyor, compressor, crusher, fan and pump motor protection, these relays boast a wide range of user-selectable protection features.

Easy to setup via a man-to-machine interface or via computer with free setup software, the user selectable settings are a pleasure to work with.

Used as either a stand alone electronic motor protection relay or as part of an automated process communicating to a PLC, the MA motor control relay is equipped with 5 digital inputs accepting field supply voltages from 24 to 220V A.C. or D.C. and 4 potential free C/O contacts, 2 of which are programmable.

Thermal curves (Class 3 to 35), to IEC 60255-8, 3 x PTC 100 inputs, Earth Leakage, Earth Fault and Short Circuit protection, Load loss protection, Over and Under Voltage protection and Voltage Symmetry are all features available through the range 5 to 250A.

The NewCode MK-1 relay is an ISO 9001:2000 compliant, locally designed and manufactured three phase electronic motor protection relay.

The relay is fully configurable with the aid of free front-end software or a man-machine interface unit (MMI).

An on-board data base stores fault and event records, which are date and time stamped. The front-end data recorder and spectrum analyzer can be used to monitor motor performance or to detect harmonics up to the 9th harmonic of any three phase currents.

The 100M Series electronic motor protection relay is a compact relay ideally suited for fitting into gate-end boxes for protecting underground coal cutting machinery and transformers.

Warning LEDs indicate when the respective threshold settings are exceeded. In the event of a trip, the respective LED and the main trip LED are latched in order to assist maintenance personnel in identifying the cause for the trip.
