Dold Monitoring Relay 3 Phase DPDT DIN Rail Mount 230V AC 400V AC IL9077.12 3/NAC 400/230V 0.1-20S

Dold IL9077.12 3/NAC 400/230V 0.1-20S Monitoring Relay is a robust industrial monitoring device designed for three-phase applications, operating within 230V AC and 400V AC nominal voltages at 50/60 Hz frequency.

This relay performs detection of over voltage, under voltage, and phase failure with network error diagnosis supported by multiple indicator LEDs for comprehensive monitoring. The response values for both over and under voltage are independently adjustable within specified ranges of 0.9 to 1.3 UN and/or 0.7 to 1.1 UN, enabling customized protection settings.

The relay features adjustable time delays ranging from 0.1 to 20 seconds, supporting precise operational timing crucial for sensitive electrical installations. The DPDT contact configuration allows flexible switching applications.

Compactly housed for DIN rail mounting, it measures 90mm in height, 59mm in length, and 35mm in width, facilitating easy integration into existing electrical panels. Terminals use screw type connectors for reliable electrical contacts. The device ensures continuous operation with an overload capability of 1.35 UN and functions effectively without auxiliary voltage and regardless of phase sequence.

The device is rated at IP40 for the housing and IP20 for terminals, providing adequate protection in industrial environments. It operates safely within a temperature range from +60°C minimum to a maximum of 60°C. The relay complies with RoHS and CE directives, confirming adherence to environmental and safety standards.

Manufactured in Malta and part of the IL 9077 series, this monitoring relay is an essential component in industrial, electrical automation, and HVAC applications where reliable phase monitoring and protection are critical.
