PRI-53

Description

PRI-53 | Three-phase relay

• It is intended for protecting the current in three-phase devices (e.g. cranes, motors, etc.).
• 24 - 240V 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, 5A).
• 6-MODULE, DIN rail mounting.
• Output relay with 2 switches contacts.
• The option of connecting via the current transformers to increase the value of the monitored current by up to 600A
