The Mack Truck and Navistar breakers are of two different styles. Some designed with an additional resistive component, this style breaker remains open as long as power is available or until the load is removed. And the other remains open as long as the overload exists and resets once power is turned off and the overload condition is fixed. It is our hope that we can supply you with all your battery related needs, and all at fair competitive prices.
