Multi Function Protection Relays
After many years of design, research, build and support, we offer a comprehensive range of multi function control relays, combining a number of protection features in one unit. Widely used in mining and general industry. And suitable for hazardous environments and providing ultimate personal protection, our relays are compliant to latest standards, including AS/NZS4871. Readily available and also able to be custom supplied, when operating conditions demand unique specifications.
Earth Leakage + Earth Continuity + Pilot Control
Combined control Earth Leakage, Earth Continuity and Pilot Control, elec is a compact din-rail mounted unit designed to detect and protect both Earth Fault Currents flowing in a power system and monitoring of the Earth Circuit in a supply cable by grounding the pilot core via a diode, polarised positive to earth.
Neutral Earth + Earth Leakage
nlm3 is a multi adjustable, advanced, din-rail compact unit designed to provide neutral Link monitoring. Compliant with latest Australian standards, nlm3 is a NER integrity protection device designed to continuously monitor the current limitation system on the secondary star point to earth connection of a supply transformer. nlm3 monitors the NER Resistance integrity, excess phase voltage rise, neutral earth leakage current, with the ability to adjust trip times for protection coordination.
Earth Fault Lockout + frozen contactor
ellfc3, is a multi adjustable, advanced, din-rail compact unit designed to monitor both Earth Leakage Lockout, Frozen contactor and under voltage, phase loss and phase rotation. Compliant to latest Australian standards, ellfc3 utilises advanced microprocessor technology and suits underground environments.
Master module combining all functions in one unit
Leaders in Innovative Protection Systems, our new Control and Protection Module CPM-Plus, represents a completely new range of single or multi-functional micro processor based intelligent relays for monitoring and protecting outlets supplying power to mining machinery.
