This equipment is extremely easy to use. You just set the test values (current, voltage, phase angle, frequency) and activate the output. When the relay's operation is detected, the chronometer will ...

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 ...

Potential relays are commonly found on many smaller, single-phase, capacitor-start, capacitor-run motors in the HVACR industry. Their function is to assist in starting the electric motor. Potential ...

It has two normally-open (‘2a’) contacts for the single-phase mains connection, which can handle 70A 277Vac with 3×10 4 minimum life, or the maximum of 80A 277Vac with 10 4 life – all with resistive ...

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 ...

At only 9.5 x 3.6 x 6.85mm, the UMS relays are about half the size of the standard MS series, but offer the same electrical characteristics as their larger SIL relay equivalent.
