Monitoring of over/under voltage (including phase breakdown):

• Installing the Electro 11 pin plug-in series of control and timing devices is simple and straightforward since they are designed to fit into a conventional 11 pin base.
• Keeps an eye on their own supply.
• The relay will only function if all three phases are present and in order and the supply voltage is between the predetermined OVER and UNDER voltage limitations.
• Supplying efficient protection and supervision for the power supply.
