Technical Data Polarized latching relay for automotive applications, with screw connections, max. 250 A Battery discharge during extended transit or storage of vehicles can lead to deterioration of the battery and subsequent warranty claims. The Gruner relay type 750 offers a simple and cost-effective solution, totally isolating the battery from the vehicles electrical circuits to eliminate quiescent drain. Another potential appli- cation is aimed at the emergency situation, such as battery isolation after a major impact. The advantage of the polarized latching relay is the pulse driven operation of only 30 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. The relays are designed and manufactured in accordance Technical data Coil data Rated voltage 12 VDC Operating voltage range 6... 16 VDC Rated switching voltage 14 VDC Rated switching current 250 A General data Ambient temperature -40 ... +110 °C Mech. shock, halfine, 11 ms, 6 directions 50 g
