Dold IL9075.12/001 Phase Monitoring Relay

The phase monitoring relay, also known as voltage monitoring relay, network monitoring relay, or phase guardian, from manufacturer Dold with type number IL9075.12/001 is an electrical protection relay for monitoring electrical systems. It has the dimensions 10 x 4 x 6 cm and weighs 0.15 kg. Phase monitoring relays serve for the reliable monitoring of three-phase networks for undervoltage, overvoltage, phase failure, and phase sequence, to protect electrical consumers and systems from damage due to network disturbances. Typical applications include motor protection, the control of pumps and fans, and general systems in automation and process technology.
