Product description

The Load monitor MK9397 and MH9397 of the varimeter family monitor reliably the load of motors as well as the function of 3 phase electrical users. If the measured value falls under or goes over the adjusted settings the corresponding output relay is energised. To avoid unnecessary tripping a response delay tv can be adjusted between 0 and 10 s. LEDs show the status of the output relays.
