Earth Continuity

iC

Earth Continuity Relay i-C, is an advanced, compact din-rail mounted unit designed to monitor the continuity of the Earth Circuit in a supply cable by grounding the pilot core via a diode, polarised positive to earth.

iC1

Combined control for Earth Continuity and Pilot Control, iC1 is an cost effective, advanced, din-rail compact unit designed to monitor the continuity of the Pilot Earth Circuit in a supply cable by grounding the pilot core via a diode. Local/Remote start operation is selectable. Compliant to latest Australian standards, iC1 utilises advanced microprocessor technology.

iC2

Providing combined control for Earth Continuity and Pilot Control, iC2 is an advanced, compact unit designed to monitor the continuity of the Pilot Earth Circuit in a supply cable by grounding the pilot core via a diode. This device is particularly suitable for operation on high voltage long distance supply cables.

Pilot Control

iD

Pilot Control Relay i-D is an advanced, compact din-rail mounted unit designed to monitor the continuity of the Earth Circuit in a supply cable by grounding the pilot core via a diode, polarized positive to earth, and to allow remote start/stop operation by momentarily shorting a 100 Ohm resistor in the pilot circuit and opening the pilot with a stop button to open the relay.

iC1

Combined control for Earth Continuity and Pilot Control, iC1 is an cost effective, advanced, din-rail compact unit designed to monitor the continuity of the Pilot Earth Circuit in a supply cable by grounding the pilot core via a diode. Local/Remote start operation is selectable. Compliant to latest Australian standards, iC1 utilises advanced microprocessor technology.

Neutral Earth

NLM3

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.

Pump Control

PCM

Pump Control Module pcm is an advanced, compact unit designed to provide submersible pump control. It monitors the current used by the pump and differentiates between load and no load currents. Two modes of operation apply. Manual mode will only switch the pump off and wait for manual switch intervention for starting the pump. Automatic mode will do full control of the pump operation by switching the pump on and off based on the level switch inputs and selected pause timer.

PCM+

Pump Control Module pcm is an advanced, compact unit designed to provide submersible pump control. It monitors the current used by the pump and differentiates between load and no load currents. Two modes of operation apply. Manual mode will only switch the pump off and wait for manual switch intervention for starting the pump. Automatic mode will do full control of the pump operation by switching the pump on and off based on the level switch inputs and selected pause timer.

Earth Fault Lockout

iG

Earth Leakage Lockout Relay i-G, is an advanced, compact din-rail mounted unit designed to detect Earth Faults on conductors in an outgoing circuit of an electrical system and to prevent the closure of the electrical supply to the de-energised circuit.

Phase Rotation

PRM

Phase Rotation/Loss Monitor Relay prm, is an advanced, compact unit designed to provide control and monitoring for phase rotation, phase loss of a 3 phase circuit. Suitable for Neutral referred circuits.

PRM+

Phase Rotation/Loss Monitor Relay prm2, is an advanced, compact unit with a remote display, that is designed to provide control and monitoring of phase rotation, phase loss of a 3 phase circuit. Suitable for Neutral referred circuits.

Multi Function Protection Relays
