Measuring relays for main monitoring
Protect individual system parts against being damaged
DOLD offers you a very wide portfolio of relays for network monitoring. The devices monitor electrical variables such as voltage, phase outage/asymmetry, neutral conductor usage, frequency as well as insulation errors. Typical uses are device and system protections, the supply of safety lighting devices, et cetera. They distinguish themselves with benefits such as space-saving thanks to their compact size, simple functionality, flexible use, high efficiency and higher operating security as well as fire and accident safety.
