• 24-240 V AC/DC power supply galvanically separated from the circuit of the monitored current
• Adjustable current level in % of In
• Fixed diff erence 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

• 2 types depending on the strength of rated current In (1A, 5A)
• 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
