Finder Series 70 Monitoring Relay, 300 to 480V AC Voltage Sensing Range, 6A Current - 70.31.8.400.2022

This monitoring relay is an advanced voltage sensing device designed for 3-phase systems. Compactly built with dimensions of 60.8 x 35 x 88.8mm, it effectively safeguards electrical installations by monitoring voltage levels and providing crucial protection against both overvoltage and undervoltage conditions.

Features & Benefits

• Accommodates a voltage sensing range from 300 to 480V AC
• Offers overvoltage and undervoltage protection for enhanced safety
• Capable of detecting phase loss and phase sequence issues
• Features a time delay adjustment of 0.5 to 60 seconds
• Equipped with coloured LEDs for clear visual fault indication
• Compact design with modular housing for easy mounting

Applications

• Ideal for wood-processing machines requiring voltage regulation
• Utilised in hoists and cranes for safe operation
• Suitable for control panels associated with pumps
• Effective for monitoring escalators and forced-air ventilators
• Employed in air conditioning systems to prevent voltage irregularities

What is the maximum operating temperature for this relay?

The maximum operating temperature for the relay is +60 °C, ensuring reliable performance even in demanding environments.

How does the phase loss detection feature work?

The phase loss detection immediately turns off the output relay when a phase is lost, ensuring protection of connected equipment, and restores the relay as soon as the phase is active again.

What adjustments can be made to enhance its functionality?

The relay allows users to easily adjust settings for voltage detection levels and delay times using a front-facing selector and trimmers, providing tailored operation.

Is this device suitable for single-phase applications as well?

This relay is specifically designed for three-phase applications and is not intended for single-phase use, optimising its performance in complex electrical systems.
