500 Amp magnetic latching switch provides high amperage switching under load, manually or from remote locations

 

• Manual override knob provides an added level of safety allowing control with or without power and offering LOCKED OFF capability for servicing
• LED output to remotely indicate switch state - requires optional LED
• 3? 8"-16 tin-plated copper studs for maximum conductivity and corrosion resistance
• 7? 8" (22 mm) stud length accepts multiple cable terminals
• Label recesses for circuit identification

Silver alloy contacts provide high reliability for switching live loads
