Descrizione del prodotto

The insulation monitor RL 5881 of the VARIMETER IMD family is a solution for optimal insulation monitoring of modern IT systems. The setting of the parameters and the switching values is done by simple and operator friendly rotational switches on front of the device. The operating status is indicated user friendly via a multicolour LED. With a sealable transparent cover the device is protectet against manipulation.
