Current and Voltage Controls
3-Phase Sequence and Phase Loss
Type EUA
• 3-phase monitoring relay for phase
sequence/phase loss (closed circuit)
• Measures when all 3 phases are present and have
the correct phase sequence
• Measures on own power supply
• Knob-adjustable level setting
• Output: Up to 3 x 5 A SPDT relay
• For mounting on DIN-rail in accordance with
DIN/EN 50 022
• 45 mm Euronorm housing
• LED-indication for relay and power supply ON
Product Description
Ordering Key
3-phase line voltage monitor-
ing and phase sequence/
phase loss relay. Adjustment
on built-in potentiometer of
monitored voltage within
±15% of rated operational
voltage. For mounting on DIN-
rail. Frequently used to se-
cure the right phase sequence
when applying a load to a 3-
phase electrical network.
