Description
Allen-Bradley 1492-H Finger-Safe Terminal Blocks
Configured for safe, insulated wiring and optional fuse indication in industrial control panels, the Allen-Bradley 1492-H (1492-H Finger-Safe Terminal Blocks) provides direct physical and electrical execution of high-density terminal connections across 1492 series assemblies.
Suffix Breakdown & Model Matrix
The 1492-H series is organized by functional variants rather than alphanumeric suffixes:
-
Fuse and surge suppressor blocks
-
High-density finger-safe blocks
-
Resistor and voltage-indicating blocks
No manufacturer-provided configurable sub-model matrix exists beyond these variant categories.

I/O Density Scaling and Panel Segmentation
1492-H blocks support high-density configurations within control panels. Finger-safe insulation maintains separation between live conductors while enabling compact row layouts. Series variants with LED or neon indication allow real-time fault diagnostics without interrupting panel wiring. Backplane bus and conductor routing must accommodate block spacing to preserve finger-safe clearance and maintain panel accessibility.
Frequently Asked Questions
Q: Can 1492-H blocks accommodate multiple wire gauges simultaneously?
A: Yes, each terminal supports wire sizes from #30 to #12 AWG (0.5–4 mm²) within the specified torque range.
Q: Does LED or neon indication require external current-limiting resistors?
A: LED or neon indicators are internally limited to maintain ≤2 mA leakage current; no external resistors are required for standard operation.
Q: Are these blocks compatible with standard 1492 DIN rails and end accessories?
A: Yes, compatible with steel or aluminum DIN rails, 1492-N37 end barriers, and 1492-ERL35/EAJ35/EAHJ35 end anchors or retainers.
Field Installation Guidelines
-
Mount blocks on a symmetrical DIN rail (steel or aluminum) ensuring full engagement.
-
Install end barriers at terminal row edges to preserve finger-safe spacing.
-
Torque each terminal screw according to 0.3–0.8 N·m range to maintain conductor retention without housing damage.
-
Verify LED or neon polarity where applicable before energizing circuits.
-
Maintain minimum clearances between adjacent conductive rows to comply with IEC/CSA spacing standards.
-
Confirm wire strip lengths of 8–9.7 mm (0.31–0.38 in) to prevent insulation creep into the terminal cavity.
