SIG JB-12 Signal Jumper Box

The signal jumper box from American Electrical streamlines field wiring with pre-jumpered push-in terminal blocks

Image of American Electrical SIG JB-12 Signal Jumper BoxAmerican Electrical, Inc. (AEI) SIG JB-12 signal jumper box is a specialized solution designed to make industrial field wiring faster, cleaner, and more organized. This innovative enclosure addresses the common challenge of distributing signals or power across multiple circuits in a compact space. Inside the box are three distinct sets of four PRD 2.5 top-entry push-in terminals. Each set is factory-jumpered to create three separate common blocks, allowing for easy distribution of power or signals without the need for manual jumpering in the field.

The SIG JB-12 is engineered for efficiency, utilizing push-in technology that ensures secure, vibration-resistant connections while significantly reducing installation time compared to traditional screw-type terminals. By centralizing these connections within a dedicated jumper box, panel builders and field technicians can maintain high standards of organization and reliability in their control systems. This product is an ideal addition to any setup requiring clean power distribution or signal branching, providing a professional finish that simplifies both initial setup and future maintenance.
