Features

  • They feature ground fault sensors that can protect machines and processes from damage caused by ground fault conditions.
  • The higher setpoint capability in these relays eliminates nuisance tripping while providing adequate ground fault detection to protect machine electronics.
  • They provide a facility for remote monitoring to discover changes in the system and protect against unnecessary downtime.
  • They also feature voltage loss restart to provide automatic revival after outages and a patented thermal design to increase motor life.

Standards and Approvals

  • UL
  • CSA

Frequently Asked Questions

What is the purpose of LED indicators in motor protection relays?

The LED indicators allow users to determine the overload status and impeding trips, providing enhanced protection to personnel and equipment.

Why are electronic overload relays considered better than traditional thermal overload relays?

Electronic overload relays surpass the thermal overload relays as they allow faster response time under phase loss and phase unbalance conditions. They increase motor life due to thermal modelling design.

How to determine that the overload relay is working?

To check the overload relay's working condition, focus on the LED indication on the relay. If it shows a single blink, then the relay is operating normally. If there is a double blink, there is a fault condition. At a glance, the user can determine the status of the overload to protect the device.
