COVID-19 - update

The health and well-being of our employees, customers and suppliers are of paramount importance to us.

We continue to monitor the latest advice and guidance from the government and are working on measures across our business to minimise any future disruption which we may experience.

Motortronics has been deemed part of the “essential” business supply chain due to the industries and customers we serve.

We have a carefully restructured operation in place to ensure continuity of service and supply and will continue to ensure that we are following latest government & health guidelines to support the health and welfare of our staff worldwide.

Our staff are available via phone, email or video conference facilities in lieu of face to face meetings.

We are continuing to monitor the situation and should anything change a member of our team will be in touch directly. For more information click here for a statement from Motortronics’ Vice President – Joyce Mitchell.

Take your motor protection to a new level. The RX Series provides more than just solid state overload or power protection relays. By using features previously found only in large expensive Motor Protection Relays, the RX Series allows even small to medium sized motor applications to be protected by the best technology available, yet at a price affordable to all.

Advanced Technology for Maximum Motor and System Protection

The RX Series uses Thermal Modeling software normally found only in the most sophisticated Motor Protection Relays. This software keeps track of power related issues occurring in the motor circuit that contribute to causing a thermal overload. If there is a power loss, a unique combination of non-volatile memory and a real-time clock ensure that this protection is in effect when power is restored. Should an overload occur, the RX Series is intelligent enough to make sure that it can only be reset when the motor is sufficiently cooled down and is ready to start again successfully. Voltage input features allow true Motor Load Monitoring, not just current, along with Power Factor, kVA and Frequency.

Built-in Flexible Control Features Provide Cost and Space Savings

A 24 hour / 7 day Real Time Clock on board allows for several additional features that can eliminate the need for other discrete devices. Duty cycle can be controlled by using the Starts/Hour and Minimum Time Between Starts features, plus a Coast-Down / Backspin timer can prevent restarting while a motor is spinning backwards. In addition, simple Batch Time processes of up to 7 events can be programmed for daily, multi-day or weekly operations without the need for an external time clock. A Restart Delay timer allows staggered restarting of multiple units as well.

Add Metering and Communications to New or Existing Starters

Metering for Three Phase Currents, Voltages, kW, kVA, kVAR, Power Factor, Frequency, kWH, Elapsed Run Time, Run Cycle Count, Lock-Out Time, Reset Time and Remaining Thermal Capacity are all included, and can be both read on the display and communicated via the built-in RS-485 Modbus RTU comm. Port. Optional converters allow communications via DeviceNet, Field Bus, Profibus and other protocols as well. Fault memory with time and date stamps helps in troubleshooting and returning to operation.
