Hiko Top Hat Frames

Hiko top hat low voltage frames are ideal for single supply customers using Tyree, Hitachi, and ETEL transformers in commercial, industry, farming and irrigation environments. The frames are designed, engineered and built for safety and reliability to deliver value throughout the asset lifecycle.

Safety is embedded into Hiko top hat frames through:

• generously sized temperature rated polycarbonate transparent covers
• latest generation EFEN fuse-switch disconnects (and optional circuit breakers and other arc-flash mitigating treatments)

Safe operating performance and long-term reliability are assured by our design methodology that includes mechanical, electrical and thermal modelling and testing, and our manufacturing process in line with the requirements of AS/NZS 61439.1 and 61439.5.

The modular range of top hat frames are available, using laser-cut stainless steel structural components and accommodating a wide range of sizes and configurations. Precision engineered designs are combined with light weight construction to support ease of installation. An almost unlimited variety is available.

Service panels are available for the top hat frame to suit customer requirements. These can be fitted pre-wired with analogue or digital metering, MDIs, street-lighting and hot water pilot wire connections and LV network monitoring systems.

Also available as 1600A DIN4 disconnects with PEN and MEN earth neutral bars.
