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

The Model SPVRB Voltage Sensing Relay is designed to protect against single phase, phase loss, phase unbalance, phase reversal, in a power system. The
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
Single Phase, Phase Reversal, Phase Unbalance and
Phase Loss Protection: Operates the output relay after a preselected time.
Automatic or Manual mode:
Automatic mode: Upon removal of fault conditions, relay automatically resets to normal.
Manual mode: Upon removal of fault conditions, relay resets to normal after local or remote
Green: Output Relay De-energized (Normal Condition)
Red: Output Relay Energized (Fault Condition)
Dark: Output relay De-energized (Input Power Off ).
