CS90423OORO Lauritz Knudsen Electronic Overload Relay REO 4G - 72 - 360 A (with earth fault protection)

The Lauritz Knudsen CS90423OORO is an electronic overload relay with an adjustable setting range of 72–360A. It protects motors against overload when used with a matching contactor.

Choose the Lauritz Knudsen CS90423OORO when your motor's full load current falls within 72–360A — or, in a star-delta starter with the relay in the winding circuit, when 0.58 × the full load current does. Setting the relay to the motor's nameplate current protects the winding from sustained overload.

Overload relays are used with contactors in motor starters, such as DOL and reversing starters, to protect motors against sustained overload.

Set the relay to the full load current shown on the motor nameplate, and make sure that value lies inside the relay's adjustable range. Choose a trip class that suits the motor's starting time. In a star-delta starter the setting depends on where the relay is connected, so follow the starter's wiring diagram.
