Current rating of 200 to 400 A enables flexible deployment across mid‑range distribution panels, letting a single insulator cover common service points and lowering inventory complexity. The porcelain construction delivers solid dielectric strength and robust mechanical integrity, reducing field failures during thermal cycling and vibration. In practical terms, this means fewer field replacements and lower maintenance costs for switchgear and bus duct assemblies. With a compact 3 inches height and 3 inches diameter, these insulators fit standard mounting footprints and integrate with common ABB Microlectric hardware. The geometry supports straightforward retrofits and minimizes changes to existing mounting brackets, speeding up installation. The porcelain body also offers superior creep resistance and long-term reliability compared with some plastic alternatives in harsh industrial environments. Access to the IB135 technical data sheet provides a definitive source of electrical ratings, environmental limits, and mounting guidance, reducing design risk. The UNSPSC 39121721 code and WEEE status help streamline cataloging, compliance checks, and end‑of‑life planning. Sourced from Canada, the product supports local supply chains and predictable procurement timelines. Two packaging levels support efficient logistics: 1 unit in the primary package and 24 units per outer carton, with dimensions designed to optimize pallet density. This packaging supports accurate forecasting, minimizes damage during transit, and facilitates bulk stocking for distributors and large electrical installers. Overall, the combination of porcelain material, defined current range, and documented data translates to reliable performance, easier maintenance planning, and a lower total cost of ownership for facilities that require stable, compliant insulators in power management and distribution networks.

FAQs
The 3 inch height and 3 inch diameter porcelain body are designed to align with common mounting footprints used in mid‑range distribution panels and switchgear. This compatibility simplifies retrofits and reduces the need for custom brackets. For installation, verify mounting bolt spacing against your existing hardware and consult the IB135 data sheet for torque and clearance guidance to prevent mechanical stress during loading conditions.
Key specifications include a current rating of 200 to 400 A, porcelain material, and a compact 3 inch height with a 3 inch diameter. Origin is Canada, and the product is documented with IB135 data sheet. The UNSPSC code is 39121721, and the WEEE classification is Product Not in WEEE Scope, which aids cataloging and compliance workflows for procurement teams.
Yes. The 200–400 A current rating is intended for medium‑voltage switchgear and distribution assemblies where reliable insulation is critical. The porcelain construction provides high dielectric strength and mechanical resilience under thermal cycling, supporting long service life in demanding industrial environments. Pairing with standard mounting hardware and confirming data from IB135 ensures correct application within your specific switchgear configuration.
The product is associated with the IB135 data sheet for technical guidance and performance specifications. It is classified under UNSPSC 39121721 and has a WEEE status of Product Not in WEEE Scope. This documentation supports regulatory alignment, accurate cataloging, and easy validation during design reviews and audits.
The porcelain insulator’s durability and defined current rating reduce field failures and maintenance cycles, contributing to lower maintenance costs and reduced downtime. The IB135 documentation provides clear installation and operating parameters, helping engineers avoid misapplication. Over the life of a distribution system, this translates to improved uptime, simpler inventory management, and a lower total cost of ownership for facilities relying on ABB insulators.
