Current monitoring relay PRI-53

AC/DCthree-phasefor electric motors

Three-phase relay PRI-53 for monitoring the current in three-phase devices 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 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 I 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
