Finder 6K.T1.0.000.2704 3-vaiheinen valvontarele, 380-690 V AC, 1 CO-kosketin

This 3-phase monitoring relay safeguards motors and equipment by continuously checking phase sequence, phase loss, and voltage levels in 380–690 V AC systems. Its adjustable thresholds for undervoltage, overvoltage, and phase unbalance, combined with a trip delay of 0.1–30 s, prevent damage from unstable power conditions.

Advantages

The relay offers a wide supply voltage range of 380–690 V AC and a single changeover contact rated for 5 A at 250 V AC. Its compact 2-module DIN rail housing saves panel space, while screw terminals ensure secure wiring. LED indicators provide clear status at a glance.

Suitable for

• Protecting three-phase motors in industrial machinery
• Monitoring power quality in HVAC and pumping systems
• Preventing phase loss or reversal in conveyor and lifting equipment
