Overview
The Allen-Bradley 1492-J3-BL is a feed-through terminal block from Rockwell Automation’s industry-leading Bulletin 1492 family of IEC-standard terminal blocks. Engineered for reliable single-pole electrical connections in industrial control cabinets and automation systems, this black terminal block combines screw-connection simplicity with proven durability. Each unit measures 5.1 × 60 × 39.5 mm and accepts 24–12 AWG conductors, making it ideal for field wiring, panel integration, and system upgrades.

Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The 1492-J3-BL is the black variant of the standard 1492-J3 and may replace gray (1492-J3), red (1492-J3-RE), blue (1492-J3-B), green (1492-J3-G), and other color variants in applications where color coding is non-critical or customizable.
Works With
- DIN rail mounting brackets and rail spacers (199-DR1, 1492-DR5)
- Terminal block accessories including jumpers and marker labels
- All major PLC platforms (Allen-Bradley CompactLogix, ControlLogix, SLC 5/05)
- Industry standard motor control and switchgear ecosystems
