Motor Protection Solutions

A) Motor Winding Heater Controller

This Series had an optional shutdown input that can be connected to the N.O. auxiliary contact on the motor starter’s thermal overload relay. This will disable the

motor winding heater control, preventing any additional heating in the motor and allowing for a faster motor cool down period. It then goes back on-line after the overload relay is reset. This Series keeps motors warm & moisture-free during extended shut down periods

Easy to Install

Whether retrofitting an existing starter or installing a new one, it is easy to apply. Just wire it in parallel to the magnetic starter’s line and load connection, connect the necessary auxiliary contacts and installation is complete.

Simple Adjustment

Output voltage is factory set to maintain a +5° to 10°C differential above ambient temperature. This adjustment can be used to trim the control as required for each application.

Self Protected

In addition to built-in fuse protection, it features an RC snubber circuit across the SCR which protects it from any rapid rate of change in the system voltage. A metal oxide varistor (MOV) protects the unit against voltage spikes for reliable, maintenance-free operation.

Fully Automatic Operation

Designed for fully automatic operation, it turns on when the motor starter has turned off. A built-in one minute timer ensures that the motor magnetic field has collapsed before it injects DC power into the windings. When the motor is restarted, the MWH Series instantly turns off. No operator interface is required.

Built-in Overload Sensing

  • This Series had an optional shutdown input that can be connected to the N.O. auxiliary contact on the motor starter’s thermal overload relay. This will disable the motor winding heater control, preventing any additional heating in the motor and allowing for a faster motor cool down period. It then goes back on-line after the overload relay is reset

Ideal Alternative to Strip Heaters

  • Eliminate the cost and hassle of installing strip heaters into your motors. Simply wire up, to generate heat throughout the motor stator windings. The heat is dissipated evenly without the “hot spots” caused by strip heaters. Conduction of heat to the rotor, bearings and shaft is also more effective which means maximized protection for the whole motor.

B) Motor Protection Devices

  • Motor Protection Relay

Take your motor protection to a new level. Our product provides more than just solid state overload or power protection relays. By using features previously found only in large expensive Motor Protection Relays, it 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

It 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, it 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.

  • Motor RTD Monitor

The TE-RTD12 Relay device adds advanced RTD (Resistor Temperature Detector) and differential current monitoring capability to your new or existing motor system. The TE-RTD12 Relay device offers 12 built-in RTD inputs, 3 programmable output relays (5A), 2 isolated analog inputs (4-20mA), 1 isolated analog output (4-20mA), 3 isolated digital inputs, and differential current feedback monitoring.

Additionally, an RS485 (2 wire) communication port is available for use with a master device (PLC / SCADA / Operator Interface) for the purpose of programming and/or monitoring.

Programmable relay outputs are provided that can be configured for a system function or for use as a global Alarm or Trip based on temperature readout, which can be entered in ºC or ºF. A built-in event recorder stores fault history of past events with data points including Alarm / Trip Code, Current / Temperature value, Analog input value and Date / Time Stamp.

The TE-RTD12 Relay device can be mounted on a back panel using the mounting bracket or DIN-Rail mount.

C) Insulation Measure and Protection unit

It is a relay that protects the system from abnormal low insulation resistance conditions in the motor and cabling. At a time when a fault is detected, it will alarm or trip the motor or prevent starting.

 

D) Electronics Motor Brake

Electronic braking stops the load by injecting a controlled amount of DC into a three-phase AC motor. The “automatic braking controller” features full wave DC braking which can be adjusted to stop your load quickly, repeatably, and reliably…even if load conditions change. Electronics brake meets the three main objectives that are important in every industry: Maximized Safety, Increased Productivity, and Maintenance-Free Operation.

E) Vacuum Contactor for Medium Voltage

  • 7.2kV Class – 400A,630 A,800 A: –

        Our Series 7.2kV Class – 400A,630 A, 800 A ‘Non-Latching’ and ‘Latching’ Series of medium voltage three-phase vacuum contactors can be used in power systems with a rated voltage up to 7.2 kV and can be used for continuous AC operating currents of up to 400 amperes. Control voltage for the contactor is AC/DC 100~125V or AC/DC 200~230V*, including an auxiliary relay with 3 NO and 2NC contacts. 

  • 12kV Class – 400, 630 and 800A:-

 Our Series 12kV Class 400, 630A and 800A, ‘Non-Latching’ Series of medium voltage three-phase vacuum contactors can be used in power systems with a rated voltage up to 7.2 kV and can be used for continuous AC operating currents of uptot 800 amperes. Control voltage for the contactor is 110~120VAC or 220~230VAC*.

This Series 12kV Class 400A, 630A and 800A Class contactors are non-latching and use constant-on electromagnetic coils to close, and hold closed the vacuum bottle contacts. When the power to the electromagnetic coil is removed, the vacuum chamber contacts spring open (termed as; electrically held contacts or non-latching contacts).
