ABB 1SVR740750R0400 Single-Functional Voltage Monitoring Relay

Description

• The ABB 1SVR740750R0400 CM-EFS.2P is a single-functional voltage monitoring relay, part of the CM single-phase monitors range. Designed to provide reliable voltage monitoring, this monitoring relay operates with a rated control supply voltage ranging from 24 to 240 V AC/DC. It features a 2 c/o (SPDT) output with contacts rated at 250 V and 4 A, making it suitable for various voltage monitoring applications.

• One of the standout features of the CM-EFS.2P is its utilization of the RMS (Root Mean Square) measuring principle, which enables it to accurately monitor both DC and AC voltages. It offers four measuring ranges, allowing it to handle different voltage levels effectively. The available measuring ranges are 3-30 V, 6-60 V, 30-300 V, and 60-600 V, making it versatile for a wide range of voltage monitoring tasks.

• This voltage monitoring relay offers window monitoring for overvoltage and undervoltage conditions, ensuring that the monitored voltage remains within a specified range. Users can also select between ON- or OFF-delay for the relay's response to voltage variations. The relay supports both open- and closed-circuit operating principles and can be configured with or without a latching function, depending on the specific requirements of the application.
