Three-phase relay PRI-53

• It is intended for monitoring the current in three-phase devices (e.g.
cranes, motors, etc.).
• 24 – 240 V AC/DC power supply galvanically separated from the circuit
of the monitored current.
• Adjustable current level in % of In.
• Fixed difference level.
• Adjustable delay level (when exceeding the preset limit).
• Adjustable function:
– UNDER – monitors the drop in the strength of current below the
preset value (I).
– OVER – exceeding the preset value (I).
• 2 types depending on the strength of rated current In (1 A, 5 A).
• 6-MODULE, DIN rail mounting.
• Output relay with 2 changeover contacts.
• Option of connecting via the current transformers to increase the
value of the monitored current by up to 600 A.
