What’s new in UniGear ZS1 single busbar?
A narrower size! UniGear ZS1 single busbar is now available in 500mm – combining the existing performance standards of the UniGear family with a narrower footprint that gives you access to more space and energy-efficiency advantages.
New form factor, same quality
UniGear is built on a reputation for reliability, safety and efficiency, spanning 25 years. 500mm wide UniGear ZS1 continues this legacy, with exactly the same component quality and uncompromising testing regime, all in a narrower footprint.A high-throughout future
As power demands grow, so does the demand for switchgear. By specifying narrower panels, you can get more value from every substation room and reserve space for future expansion – so you’re ready for anything.Smart, proven technology
The 500mm wide UniGear ZS1 offers smart, energy-saving sensors for protection, monitoring, and automation. Proven in China, it now enters IEC markets with updated specs and more recyclable components.Medium Voltage Sensors for UniGear ZS1
ABB’s AdvaSense™ medium voltage indoor sensors—also known as Low-power Instrument Transformers (LPITs)—use Rogowski coils or voltage dividers to replace conventional transformers. These compact, safer alternatives offer standardized ratings and expanded functionality, especially when paired with Intelligent Electronic Devices (IEDs) like protection and control relays.
