in a power system. The output contacts change their normal state only when a phase loss, phase unbalance, phase reversal, under or overvoltage occurs for
longer than the preset trip delay. A total power loss de-energization of the SPVRA relay will not change the output contact position. Recommended for
manually reset switches and breakers applications. The SPVRA is suitable for loss of phase with motor loads.

The Model SPVRA Voltage Sensing Relay is designed to protect against single phase, phase loss, phase unbalance, phase reversal, and under or over voltage
Phase Unbalance: 8 %
Adjustable Trip Delay 1 to 10 seconds after failure occurs.
Output Relay: normally de-energized: Form C contacts for easy circuit conf iguration.
Electro - Mechanical Indicator: retains memory of fault until manually reset .
Door or Panel mounting.
Status Indicator: bi-colored LED
Green: Output Relay De-energized (Normal Condition)
Red: Output Relay Energized (Fault Condition)
Dark: Output relay De-energized (Input Power Off ).
Single Phase, Phase Reversal, Phase Unbalance and Phase Loss Protection: Operates the
output relay after a preselected time.
Overvoltage and Undervoltage Protection: Operates when voltage exceeds 115% or goes
below 80% after a preselected time.
Automatic or Manual -
Automatic Reset to Normal: upon removal of fault conditions.
Manual Reset: Operations from a local pushbutton in cover or from a remote contact .
