Checking for live stock

The Schneider Electric RMNF22TB30 is a three-phase monitoring relay engineered for advanced protection of industrial power systems. It supports line-to-line voltages of 208–480 V AC (and line-to-neutral 120–277 V AC) and carries switching capability up to 8 A with dual changeover (2 CO) contacts. Featuring integrated monitoring for under-voltage, over-voltage, phase loss, phase reversal, and frequency deviations, it is designed for high-demand control panels, machine tools, pumping systems, and infrastructure applications that require precise, continuous power-system oversight. Its modular DIN-rail form factor, combined with NFC-enabled configuration, makes it suited for modern switchboard setups and smart maintenance routines.

What Benefits Does It Offer to Users?

Monitors three-phase systems for phase loss, sequence and asymmetry, improving system integrity.
Detects undervoltage and overvoltage, helping prevent equipment damage and downtime.
Supports line-to-line 208–480 V AC and line-to-neutral 120–277 V AC, offering broad voltage flexibility.
Contains 2 CO contacts rated at 8 A, enabling reliable output switching.
Adjustable time delay (from 0.1 s up to 3,600 s) to tailor protection behaviour for specific operations.
NFC-based configuration streamlines setup and maintenance in smart systems.

Engineered for Continuous Industrial Operation

The high-capacity relay is prepared to handle demanding industrial environments. With protections against phase faults and voltage anomalies, the relay helps maintain continuity, reduces the risk of damage to downstream equipment, and supports predictive maintenance workflows via NFC programmability. These features combine to reduce service downtime and extend system lifecycles.

Applicable Areas of the Schneider Electric Voltage Monitoring Relay, 3 Phase

Monitoring and protection of three-phase motor starters in manufacturing machines.
Voltage and phase supervision in industrial distribution panels or MCCs (Motor Control Centres).
Automation systems where phase-sequence integrity is crucial (e.g., lifts, conveyors, cranes).
Renewable or utility integration systems.
