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
