Panasonic Electric Works will soon release a 200A EV relay for electric drive trains, closing the gap between the 120A and 300A types. The 200A relay can carry 200A continuously or 300A for 15 minutes. Higher peak currents, due to acceleration of vehicle for example, for a few minutes or seconds are possible much beyond 200A. This means many sport cars and light commercial vehicles can be realized with this main contactor.
The 200A EV is build up on the proven design and continuously developed EV relay family. Its contacts are integrated in a hermetically-sealed ceramic chamber. This contact chamber is constructed of high quality ceramic that separates the arc from other components, electrically and thermally. The chambers superior mechanical stability increases the system safety even in the event of a malfunction.
Another special feature is that the contact chamber, including the actuating mechanism, is encapsulated and permanently filled with hydrogen gas.
