Frequently Asked Questions about 1492-JD3FB
Question: What are the key features of the 1492-JD3FB?
Date Update:13/06/2025
Answer:

This terminal block includes:

  • Two-level structure for efficient space usage
  • Hinged-arm fuse circuit for integrated protection
  • Screw terminals compatible with 14 AWG conductors
  • Mounts on 35mm DIN rails
  • Voltage ratings: UR/CSA 300V, IEC 500V AC/DC
  • Amperage rating: 10 amps
  • Certifications: UL, CE, CCC, CSA, KC

These features enable versatile and safe installation in automation panels.

Question: How does the two-level design improve wiring?
Date Update:13/06/2025
Answer:

The dual-level structure of the 1492-JD3FB offers multiple advantages:

  • Top and bottom connection points for routing power and control wires
  • Feed-through circuit allows uninterrupted connections across terminals
  • Integrated fuse arm separates protected circuits from standard conductors
  • Reduces panel space by eliminating the need for separate fuse holders
  • Supports compact and layered wiring in high-density terminal strips

This design streamlines wiring and simplifies maintenance in control systems.

Question: Does the block support field-replaceable fuses?
Date Update:13/06/2025
Answer:

Yes, the 1492-JD3FB is designed with a hinged arm that accommodates standard glass or cartridge-style fuses. The fuse can be easily replaced without removing the entire block from the DIN rail. This design allows technicians to quickly service blown circuits with minimal disruption. The hinged mechanism keeps the fuse securely in place under vibration. It's ideal for protecting control circuits, sensors, and signal lines.

Question: Which wiring sizes are compatible?
Date Update:13/06/2025
Answer:

The 1492-JD3FB supports:

  • 14 AWG conductor size
  • Screw terminal connections for solid or stranded copper wires
  • Standard insulation types within the rated size range
  • Secure fastening to prevent loosening in high-vibration settings
  • Use of proper wire ferrules is recommended for reliability

This ensures flexibility for general-purpose industrial wiring.

Question: Is the 1492-JD3FB still in production?
Date Update:13/06/2025
Answer:

Yes, the 1492-JD3FB is actively in production and widely available through Allen-Bradley distributors. It remains a key product in the 1492 terminal block family, supporting ongoing use in control panel projects.
