PRI-52 / Current monitoring relay PRI-52

The current transformer relay, which senses the current through the passing wire, is used to diagnose a remote device (short circuit, increase of consumption), to indicate the current flow or to connect the appliances to the inverter performance in photovoltaic applications.

DESCRIPTION

• Current transit indicator – informs about heating activation, ceramic hob, ventilator.
• 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).
• Hole for threaded conductor passes through the body of device.
• Possible to use also for sensing of current up to 600A from external current transformer.
• 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.

TECHNICAL PARAMETERS

• Power voltage AC 230 V
• Output contact: 1x changeover 8 A/AC1 (AgNi, 2500 VA)
• Slight setting (by potentiometer ) of tripping current – range AC 0.5….25A
• Slight setting (by potentiometer) of delay – adjustable in range 0.5…..10s.
• 1-MODULE, DIN rail mounting.
