Replaces / Drop-In Replacement For
The 1492-J3-BL directly replaces earlier-generation 1492-J3 terminal blocks in grey. All 1492-J3 color variants (1492-J3, 1492-J3-RE, 1492-J3-B, 1492-J3-G, 1492-J3-Y, 1492-J3-OR, 1492-J3-BR, 1492-J3-W, 1492-J3-V) maintain identical mechanical and electrical specifications and mounting dimensions, allowing straightforward substitution for circuit identification or stock replenishment.
Works With
- DIN rail mounting systems and accessories (199-DR1, 1492-DR5)
- Rockwell Automation cabinet design standards and safety protocols
- IEC 60999-1 terminal block standards for screw-type connections
- Industrial control systems using modular terminal block architecture
