Allen-Bradley 1492-H5 Finger-Safe Fuse Terminal Block with LED Indicator

Overview

The 1492-H5 (1492-H5) is a high-density, rail-mounted fuse terminal block designed for the 1492 Finger-Safe wiring system. This single-pole component provides essential circuit protection for control-level signals. It features an integrated blown-fuse indicator to accelerate troubleshooting by providing a clear visual signal when a circuit interruption occurs. Engineered with a compact footprint, it ensures high-density wiring efficiency while maintaining strict safety standards for electrical contact prevention.

Application and Maintenance

The 1492-H5 (1492-H5) is primarily used in control panels for protecting PLC I/O points, solenoid valves, and sensor loops. The finger-safe design minimizes the risk of accidental contact with live energized parts, making it ideal for high-traffic industrial enclosures. The screw-clamp mechanism is optimized for high vibration resistance, ensuring long-term connection integrity in demanding environments such as motor control centers and distributed I/O stations.

Engineering FAQ

• What type of fuse is compatible with this holder?The 1492-H5 (1492-H5) typically accepts standard 1/4 inch x 1-1/4 inch (6.3 x 32 mm) fuses. Always verify the specific fuse dimensions against the holder clip tension.

• Does the LED indicator require a separate power source?No, the leakage current through the LED circuit across the blown fuse provides the illumination. Note that a small amount of leakage current (typically <2mA) will exist when the fuse is blown.

• Is this block compatible with standard 1492-H jumpers?Yes, it integrates with the standard 1492 series jumper system, allowing for efficient commoning of power or ground across multiple adjacent blocks.
