Polarized latching relay for automotive applications, with screw connections.
Modern LiIon car batteries require a battery disconnect switch for safety resons. The Gruner relay type
760 offers a simple and cost-effective solution, totally isolating the battery from the vehicles electrical circuits, such as battery isolation after a major impact.
The advantage of the polarized latching relay is the pulse driven operation of only 50 milliseconds to set and reset the relay, which results in low power consumption of the coil and no heating to the coil. The permanent magnet of the armature guarantees the extremely high holding force of the contacts which results in good vibration resistance. Furthermore the relays feature an integrated contact monitoring.
The relays are designed and manufactured in accordance to the Standards of IEC 61810-1.
