Application Group

High Inductance control

These applications require current ON/OFF control.
Therefore, 1 Form A or 1 Form U type is recommended as the contact configuration.
Basically, one single relay is recommended for ON/OFF control.
Also, due to the large inductance value of the load, it is recommended to use a relay contact protection circuit.

  • 【Recommendation】 Replacement of Plug-In Relay ⇒ PCB Relay

Because of the advantage of compact/lightweight, the cases of using PCB relay is gradually increasing.

*Printed Circuit board relay (PCB): A type of relay that is mounted directly on the printed circuit board

*Plugin relay: A type of relay that can be inserted and removed from the socket

Applications

  • Air conditioner clutch
  • Starter motor
