Description

Arteche Latching relay BF-4 Arteche Auxiliary Relays

Latching relay BF-4 : Relays with two stable positions. Required when the position memory (open-close, automatic-manual, local-remote…) is needed.

Latching Relays / Electrical Reset / Electrical & Hand Reset

Relays with two stable positions maintained by a permanent magnet, which prevents intermediate positions and assures reliability:

Range from 3 to 16 contacts, with extended voltage range and including visual indication of the position of the contacts

››Existing variants for overvoltage coil protection and 16 contacts

››Operating time < 20 ms

››No consumption in permanence, only during the change of position

››High breaking capacity of the contacts

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. Latching relays have no consumption in stable states.

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.

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
• RP models: Trip and lockout relays, with electrical and hand reset
• BB models: Overvoltage protection in parallel with the coil

Arteche plug-in auxiliary relays are designed to operate under demanding conditions, in locations where performance, reliability and security are a must, being suitable for systems requiring the highest safety level: SIL-4.

Our offer includes a complete range of instantaneous, latching, time delay and contactor relays to meet each application requirement. Installed in more than 150 countries, our auxiliary relays are the best choice for applications such as safety critical logics in nuclear power plants, galvanic isolation between circuits or interface, contact multiplication and remote commanding.
