Current monitoring relay
PRI-51

Serves for monitoring of heating in rail-switches, heating cables, consumption of one-phase motors, indicates current flow

DESCRIPTION

  • In suitable wiring, it can act as a power cutter for the power reserve and allow you to reduce the size of the main circuit breaker (and thus the amount of payment for this circuit breaker).
  • The design reduces the thermal stress of the product compared to the conventional solution with the built-in shunt, increases the current range up to 20A and galvanically separates the measured circuit.
  • Supply from monitored voltage.
  • In conjunction with the supplied current transformers, the basic current ranges can be expanded, increasing the range of use. 
  • Preferred (priority) relay – two appliances (boiler and floor heating) operating on one phase, but never run together – prevention against current overload and circuit breaker tripping. Enables to save your main breaker expenses.
  • Supply is galvanically separated from measured current.
  • Slight setting (by potentiometer ) of tripping current, choice from 8 ranges:

PRI-51/0.5A: AC 0.05 – 0.5 A
PRI-51/1A: AC 0.1 – 1 A
PRI-51/2A: AC 0.2 – 2 A
PRI-51/5A: AC 0.5 – 5 A
PRI-51/8A: AC 0.8 – 8 A
PRI-51/10A: AC 1 – 10A
PRI-51/0.1 – 10A: AC 0.1 – 10 A
PRI-51/16A: AC 1.6 – 16 A
