3-Phase Monitor

 

• DPDT 600VAC Output Contacts
• Adjustable Failure Level
• Automatic Reset
• 5 Year Unconditional Warranty

 

Description

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.
