AutomationDirect: Phase and Voltage Monitoring Relays

July 18, 2022

AutomationDirect has added new phase and voltage monitoring relays from ProSense. The PMRU-2C series true RMS phase monitor relays protect 3-phase equipment from damage that can occur when there is a phase loss, phase reversal, phase unbalance, undervoltage, or overvoltage condition. These relays are designed to provide protection for most generator systems and applications that use non-sinusoidal waveforms. With non-sinusoidal waveforms, the true RMS voltage measurement ensures accurate sensing, eliminating nuisance tripping.

Also added are voltage monitor relays for AC single-phase (50 to 60 Hz) or DC circuits to protect equipment from voltage faults. Over/under voltage relays, with fixed or adjustable time-delay drop-out, offer protection from over-or under-voltage conditions. Voltage band relays protect equipment required to operate within an upper and lower voltage limit. The relay is energized if the monitored voltage remains within the adjustable range.

The new ProSense PMRU-2C Phase Monitoring Relays start at $79.00, and the ProSense Voltage Monitoring Relays start at $65.00. All new relays have a one-year warranty.

Hammond Manufacturing: Type 12 Lay-In Wireway

Introducing the Type 12 Lay-In Wireway from Hammond Manufacturing, designed to enclose and protect electrical wiring from dirt, dust, oil and water. All sections and fittings of the wireway are completely open on each side to allow wires and cables to be placed into the wireway without ‘pulling through’. The Type-12 has UL 870 Type 1 and CSA Type 1 standards, unless marked, and complies with NEMA Type 12 and IEC 60529, IP54 standards.
