NAMTECH has introduced the Symcom range electric motor protection equipment to the Australian steel, power, mining and manufacturing industry.
Simple motor protection devices such as thermistors don't protect motor and pump equipment from the serious faults that are the primary cause of damage and failure. Symcom devices provide programmable motor protection, control, and communication.
Any sized motor susceptible to phase loss, voltage fluctuations, reversals and imbalances can be monitored and, upon detection, the motor disconnected from the source preventing productivity outages. Contactors controlling the motor may also be checked for integrity of supply. The motor will be automatically restarted if required once the fault is clear.
Symcom has added to the range the ability to multiplex up to 99 protective devices to a PC from which history, kilowatt averages, current, voltage and other data can be retrieved and stored on a Windows platform. Setpoint changes can be also be made from the host or at the device itself.
The basic Model 777 MotorSaver is a fully programmable electronic overload relay designed to monitor and protect three phase systems. Digital programmability allows the unit to be fine tuned to protect any given application or electrical environment. SymCom's overload relays combine sophistication with affordability, offering flexible, reliable and cost effective three phase motor protection solutions.
The equipment is also digitally programmable for precise customising. It has sixteen set points which can be programmed for maximum protection and an RS485 communications port for use with computerised systems using Modbus protocol. Recordable voltage, current, last four faults, kWh usage, and power factor are also available when using the communications package. Its last fault memory provides instant trouble-shooting diagnostics. It is UL and cUL listed as an overload relay and tested to UL 1053 as a Class 2 Ground Fault Monitor.
Other models in the MotorSaver series include relays for use on single and three phase systems with control voltages to 600Vac and applications to 800A.
