Product Overview

The Allen-Bradley 1492-N37 is a critical safety accessory within the Bulletin 1492 industrial wiring line. This high-density end barrier provides necessary electrical insulation and mechanical separation at the end of a terminal block assembly or between adjacent circuits of different potentials. It effectively prevents accidental contact with live components and ensures that your control panel meets stringent finger-safe requirements. We offer these units as 100% Brand New and Original, ensuring your automation system adheres to factory-specified safety and durability standards.

Technical Specifications

The 1492-N37 utilizes high-grade thermoplastic materials designed to withstand the rigors of industrial cabinet environments.

Engineering Advantages

• Circuit Isolation and Safety: The 1492-N37 physically blocks access to the open side of the last terminal block in a row. This prevents "creepage" and ensures that technicians cannot inadvertently touch energized parts, directly assisting in UL 508A cabinet compliance.

• High-Strength Thermoplastic Housing: Constructed from Polyamide 6.6, this barrier resists mechanical stress and chemical exposure. The UL 94-V0 rating confirms its self-extinguishing properties, which prevents the spread of fire within an electrical enclosure during a fault condition.

• Simplified Organization: Use these barriers to visually and physically segment different functional groups within a high-density wiring array (e.g., separating 24VDC logic from 120VAC power). This reduces the likelihood of wiring errors during field installation and future maintenance.

• Precision Snap-On Fit: The barrier matches the profile of Bulletin 1492 finger-safe terminal blocks exactly. It snaps onto standard DIN rails without tools, providing a flush finish that stabilizes the entire terminal assembly against lateral movement.

FAQs

Q: Why do I need an end barrier like the 1492-N37?

A: Terminal blocks typically feature one open side to save space and material. When you reach the end of a rail assembly or want to separate different voltages, the 1492-N37 closes that open side. This prevents short circuits between adjacent blocks and protects personnel from electrical shock.

Q: Which specific Allen-Bradley terminal blocks work with the 1492-N37?

A: This barrier is specifically designed for the Bulletin 1492 line, including the H-series (H4, H5, H6, H7). It also serves as an isolation barrier for single-circuit fuse blocks and standard feed-thru blocks within that ecosystem.

Q: Does the material degrade in high-temperature environments?

A: No. The Polyamide 6.6 material maintains its structural integrity and dielectric strength up to +85 degrees Celsius. It also remains flexible enough to prevent cracking in cold-weather applications down to -40 degrees Celsius.

Q: Are these sold individually or in bulk?

A: While factory packaging typically contains 50 units, we often provide these in "Lots of 10" to accommodate smaller project requirements. Every unit in the lot is guaranteed brand new.
