REQ650 - Breaker protection

Longer life and cost efficiency for your installations

REQ650 provides you with an ideal backup protection. The breaker failure protection allows for high speed back-up tripping of surrounding breakers, and re-tripping of the own breaker. This function is essential in substations that require local back-up protection. Breaker protection REQ650 is also the perfect choice for refurbishment projects where old protection relays need to be replaced.

REQ650 – ease of use from ready-to-use solutions

REQ650 offers optimum ‘off-the-shelf’, ready-made application solution for the protection and control of circuit breaker connected objects. The type-tested variant is delivered equipped and configured with complete protection functionality, and with default parameters for easy handling of products – from ordering, engineering and commissioning to reliable operation.

The 650 series IEDs (Intelligent Electronic Device) has a number of useful features, such as a significantly reduced number of parameter settings and extended IED HMI functionality, including 15 dynamic three-color indication LEDs per page, on up to three pages, and configurable push-button shortcuts for different actions.

In the 650 series IEDs, most basic parameters are set before delivery from the factory. You only need to set the parameters specific to your application. This allows you to quickly take your IEDs into operation. The application manual includes setting examples to support your protection engineers.
