Innovative news for mains- and plant protection in the area of renewable energies are our new and safe voltage/frequency monitor RP 9811 – adaptable on many norms in different countries including the VDE-AR-N 4105- of our series VARIMETER NA as well as the differential current monitor IP 5883 of our series VARIMETER RCM – for
grounded systems. The new insulation monitors LK 5894 of our series VARIMETER IMD - for ungrounded DC/AC systems or mixed systems can be used for high voltage and leakage capacity.

Our 17,5 mm wide hybrid switching relay IK 3070/200 - the ideal combination between mechanical relay and semiconductor switch – for switching high capacitive or inductive loads with high inrush currents, eg at energy saving lamps.

DOLD - innovative solutions in the safe automation, in the motor control as well as in measure- and monitoring
technology for building automation - use your chance to get competent and efficient information.

We look forward to meeting you!
