EX2638
The Model 2638 3-Phase Monitor combines a 3-phase monitor with a line voltage and phase sequence indicator. Like other Time Mark Monitors, the Model 2638 senses phase loss, phase reversal and low voltage.When power and phasing are correct, the internal relay energizes. LED indicators will show that all phases are present, and the direction of phase rotation.
When a fault occurs, the monitor trips its relay and indicates which phase is lost, or, if a reversal is present. This allows you to automatically protect your equipment by correcting the appropriate fault condition.
The Model 2638 will automatically reset when correct power is restored. It is available in 208/240 VAC, 480 VAC, or 380 VAC/50 Hz.

EX2594
The Model 2594 3-Phase Monitor is designed for use with applications which require high control voltage (up to 600VAC). The Model 2594 protects 3-phase equipment and motors from phase loss, phase reversal and low voltage. When the correct voltage and phase rotation is applied, an internal DPDT relay energizes.A fault condition drops out the relay and the FAILURE INDICATOR LED illuminates. When the existing fault is corrected the unit will automatically reset. The Model 2594 can detect a phase loss condition even when regenerative voltage is present. It may be used with Wye or Delta systems; no neutral connection is required.
Standard operating ranges are available from 120 to 575 VAC, 60Hz, and 380VAC, 50Hz.
