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.
