Lighting contactors are available up to 400a and diffinite purpose contactors shoulde be also. I'm assuming you're talking about 480vac. Usually when one inquires about a product one includes the voltage rating of the device in question, the numer of poles, the type of load, latching of magnetically held, coil voltage as will a the current requirement. Otherwise, should an answer be provided based upon limited information the answer is likely to be incorrect for the actual application.
