The 7-1618401-8 is an EV200P series latching contactor designed for high-voltage DC switching. This specific model features a 12 Vdc coil, a latching SPST contact form, and bottom mounting with male M8 threaded power terminals. It is rated for a continuous current of 500A and a maximum voltage of 750 Vdc across its main contacts. As a hermetically sealed device, it provides reliable operation in harsh or explosive environments by preventing oxidation or contamination of the contacts over long periods of non-operation. Its robust design is ideal for applications requiring high current and voltage control, such as battery storage systems, power distribution, and electric vehicles.
