Latching Relays

Latching relay with visual position indicator

Latching relays are relays with 2 stable positions for the output contacts. Depending on which coil is energized, the output contacts will change from one position to another. Arteche latching relays have no consumption in permanence.

Thanks to their design and constructive characteristics, Arteche latching relays provide reliability, security and high performance for most demanding application in power, railway and industrial markets.

The performance of their contacts and the overvoltage protection allow them to operate high and medium voltage primary equipment, providing a perfect galvanic isolation.

Arteche manufactures latching relays from 3 to 16 contacts (BF-3, BF-4, BJ-8, BI-16) for general purpose and offers a wide range of characteristics to fit each application requirements:

  • R models: Trip and lockout relays, with electrical reset (i.e. BF-3R, BF-4R, BI-16R)
  • RP models: Trip and lockout relays, with electrical and hand reset (i.e.: BF-4RP, BJ-8RP)
  • BB models: Overvoltage protection in parallel with the coil (i.e.: BF-3BB, BF-4BB, Bi-16BB)

Arteche also manufactures FF series latching relays, a product range specially designed to meet the most demanding requirement of railway industry. To learn more please visit auxiliary relays for railway applications.
