Reverse Rotation Stop Relay APR-S

Reverse Rotation Stop Relay APR-S

Reverse rotation prevention relay APR-S

[Features]
· Voltage detection method three-phase motor reverse rotation prevention relay.
· Relay that prevents reverse rotation resulting from erroneous wiring.
· When powered on, it distinguishes between positive-phase, reverse, and reverse-phase.
· Magnet contact is prevented.
· With the wire connection method, open phase input is also prevented.
· Small plug-in type, with no adjustment needed.
· Because of the voltage detection method, it can be used irrespective of the load current.

APR-S external connection example

Operation description
When power lines R → S → T are energized to apply current in sequence to terminals (6) → (4) → (3) there is a positive phase sequence.
Positive phase sequence: built-in relay operation ((5)-(1) carrying current, (5)-(8) not carrying current).
Negative phase sequence: no built-in relay operation ((5)-(1) not carrying current, (5)-(8) carrying current).

  • *For applied voltages and control voltages to contacts use a separate power supply.

Operation description
When power lines R → S → T are energized to apply current in sequence to terminals (10) → (1) → (3) there is a positive phase sequence.
Positive phase sequence: built-in relay operation ((6)-(7) carrying current, (6)-(8) not carrying current).
Negative phase sequence: no built-in relay operation ((6)-(7) not carrying current, (6)-(8) carrying current).
