In almost every Industry electrical motors are invariably used to drive machineries & equipments. A breakdown of motor can cause huge productivity losses as well as loss of time & money in maintenance for any industry either a small work shop or process industry.

Â It is therefore preferable to prevent a motor failure before it can cause heavy losses.

Conventional motor starters & relays can prevent such failure of motor to some extent, but can not protect the motor against various other reasons of failures like frequent starting/stopping, current & voltage unbalance, Over Current, Overheating, single phasing, earth leakage.

As a solution to this most common problem of motor failure R K Electronics Enterprise Products has come up with series of microprocessor based Motor Protection Relays having multi-parameter monitoring & smart logic with user customizable parameters. There are various models to select from based on motor capacity as well as based on various additional features like fault annunciation, event register or fault log with retrievable trip status.

This product not only provide 100% motor protection but also provides very important data about motor power consumption as well as data about trip for analysis of fault.
