No Volt relay

Finder Make 70 Series: Line monitoring relays for single and three-phase applications.

Finder offers a new range of Electronic voltage monitoring relays for single and three-phase application - in 17.5 or 35 mm housings.
Types 70.11, 70.31 and 70.41 cover the following functions and points of specification:

• Models for the multi-function control of undervoltage and overvoltage, phase sequence, phase loss, asymmetry and loss of neutral
• Positive safety logic (the contact opens when the monitored parameter is outside of limits.
• All functions and values can be easily adjusted by the selector and trimmer on front face
• “Blade + cross” – both flat blade and cross head screw drivers can be used to adjust the regulators, the function selector, and to release the 35mm rail catch
• Colored LEDs for clear & immediate visual indication
• 1 CO relay output, 6 or 10 A
• Compact module sizes (17.5 mm or 35 mm wide)
• Mounting on 35 mm rail (EN 60715)
• Cadmium Free contacts

These relays join the type 70.61 for three-phase loss and rotation (replacing the type 72.31 as reported in the Finder News January 1 2012).

European Patent pending for the innovative principle at the root of the 3 phase monitoring and error survey system.

The 70.61 technical characteristics are as follows:

• Universal voltage monitoring (UN from 208 V to 480 V, 50/60 Hz)
• Phase loss monitoring, even under phase regeneration
• Positive safety logic - Make contact opens if the relay detects an error
• 1 CO relay output, 6 A
• Compact size (17.5 mm wide)
• 35 mm rail (EN 60715) mount
