Overview
The Allen-Bradley 1494F-N21 Multiple Door Auxiliary Interlock Kit, Series A is an industrial-grade safety accessory engineered to coordinate mechanical interlocking across multiple enclosure doors. This auxiliary door interlock kit integrates with 1494F fixed-depth flange-mounted disconnect switches to prevent dangerous simultaneous door access. The kit ensures operator safety by physically restricting door movement, meeting strict regulatory requirements in machine guarding and electrical safety applications.
