Allen-Bradley 1495-N43 Electrical Interlock

The Allen-Bradley 1495-N43 Electrical Interlock is a Rockwell Automation accessory kit that provides an electrical interlock for 1494-series disconnect switches, specifically designed for 1494V and 1494C models with a right-hand mechanism. It features a 1 normally open (N.O.) and 1 normally closed (N.C.) contact pair to coordinate the disconnect’s operation with the control circuit, enabling safe sequencing in industrial switchgear. Cataloged as 1495-N43 (stock reference #266493 in some listings), this interlock is commonly used in motor control centers and other panels that rely on 1494 disconnect switches for safe isolation. By adding the 1495-N43 interlock, operators can implement interlock logic between the switch handle and the control circuit, helping ensure that the switch cannot be moved through unsafe sequences and improving protection for personnel and equipment.
