Bender - RCMA471LY - AC/DC Sensitive Residual Current Monitor, 30 mA–3 A

The Bender RCMA471LY is an AC/DC sensitive residual current monitor designed for detecting residual currents in earthed systems (TN and TT systems). Key features include:

• Monitoring Capability: Suitable for AC, DC, and mixed systems, capable of monitoring both single-phase and three-phase systems. 

• Adjustable Response Value: Stepless adjustment from 30 mA to 3 A, allowing flexibility across various applications. 

• Response Delay: Adjustable delay settings to accommodate specific system requirements. 

• Alarm Relays: Equipped with two relays, each with one change-over contact, for main alarm and pre-warning functions. 

• LED Indicators: Features an LED bar graph indicator displaying real-time residual current as a percentage of the set response value, along with status LEDs for power and alarm conditions. 

• Test and Reset Functions: Integrated TEST and RESET buttons, with options for external activation, facilitating straightforward operational checks and fault resets. 

• Mounting: DIN rail mountable, facilitating easy integration into control panels and switchgear assemblies. 

This residual current monitor is ideal for applications requiring continuous monitoring of residual currents to enhance electrical safety, prevent equipment damage, and reduce downtime in industrial and commercial installations.
