Reverse Protection Relay

APR-S

Uses Voltage Detection to Determine Reverse Revolution of Three-phase Motor

Detects motor reversal due to incorrect wiring.

Direction of motor revolution is detected as soon as power is applied to the Relay. If the power is reversed, the magnetic contactor locks in the open state.

The magnetic contactor can also be wired to protect it from being closed in open phase.

Small, plug-in Relay that needs no adjustment.

Uses voltage detection method to operate independently of load current.
