Industrial Phase Monitor Relay

The Schneider Electric RM17TA00 is a DIN-rail voltage sensing relay designed for three-phase mains monitoring. It accepts a control range of 208 to 480V AC and uses a single SPDT contact rated at 3A at 250V AC or 5A at 24V DC. The six-pin unit automatically restarts after a fault clears.

Suits panels needing phase-loss

Installers protecting motors or pumps from phase loss, phase reversal or adjustable unbalance between 5 and 15 percent will find this relay appropriate. Buyers who require dedicated over-voltage or under-voltage trip functions cannot use this model because those features are absent.

SPDT contact form with 6-pin DIN-rail mounting

The single-pole double-throw output and six-pin DIN-rail footprint determine whether the relay fits the existing control panel wiring and enclosure layout. Verify the contact form and pin count against the schematic before ordering.

Questions about this item

Will the phase-unbalance adjustment need recalibration after the relay has been running for months?

The phase-unbalance setting is adjustable from 5 to 15 percent and is a fixed mechanical adjustment; it does not drift or require periodic recalibration.

What is the first limit reached when the relay operates continuously at its maximum AC contact rating?

The AC contact rating of 3 A at 250 V is the limiting factor; exceeding this current will cause the relay contacts to overheat before any other parameter is reached.

How much heat does the RM17TA00 generate when mounted on a DIN rail and powered 24/7 at 480 V AC?

The unit draws only the control-circuit current at 208–480 V AC, so heat output is minimal and typically does not require additional ventilation in a standard enclosure.
