Compact and cost-effective switchgear for standard applications in primary power distribution

PrimeGear ZX0 is part of ABB’s gas-insulated indoor switchgear for primary distribution. PrimeGear ZX0 is a cost-effective switchgear that distributes medium voltage electric power safely and reliably. It is ideal for standard primary applications where space is limited. It is fully compliant with the IEC and GB standards. ABB offers PrimeGear ZX0 SF6-free, complying with the EU F-gas regulation (EU) 2024/573, up to 12kv.

A compact and cost-effective gas-insulated switchgear for primary distribution built as a three-phase encapsulated, arc-resistant switchgear for single busbar applications. PrimeGear ZX0 is suitable for a variety of conditions, including high altitudes (higher than 1000 m above sea level) and extreme operation conditions (-15°C).

PrimeGear ZX0 with SF6

PrimeGear ZX0 with SF6 gas (Sulfur hexafluoride) as insulation medium. The SF6 gas is contained in a welded stainless-steel enclosure.


ABB’s complete transition to SF6-free switchgear will be phased in line with our ambitious sustainability targets, evolving regulatory deadlines, market demand, and production capacity

PrimeGear ZX0, SF6-free

PrimeGear ZX0, SF6-free up to 12kv, with dry air as the insulation medium with a GWP >1. This variant is compliant with the EU F-gas regulation (EU) 2024/573. 

PrimeGear ZX0 with dry air offers the same interface, footprint and operations as the SF6 version.

Simple, cost efficient and compact design for standard applications, while compliant with F-gas regulation

  • Compliant with IEC and GB standards and with the EU F-gas regulation (EU) 2024/573 – based on dry air
  • Cost-effective ideal for standard applications in primary distribution. Single busbar modular compact low-pressure design, based on dry air for the SF6-free variant.
  • Compact low-pressure design – some panels able to operate at low pressure (1.0 bar abs.). Space saving wall-mounted installation possible making it ideal for containerized substations.

Reliable and flexible

  • Very low maintenance switchgear as all high voltage parts are permanently protected in a gas tank from soiling, humidity, entry of foreign bodies and other environmental influences.
  • Able to operate in a variety of non-standard temperatures and climatic conditions, including high altitudes (higher than 1000 m above sea level) and extreme operation conditions (-15°C).
  • Automation and control features through current and voltage sensors and monitoring and diagnostics capabilities (temperature, gas, partial discharge, etc).

Safe and reliable

  • Extra safety margin with 1.0 bar abs. as minimal operational pressure allowing continuous operations even in the case of low-level gas
  • High level of operator safety with front, lateral and rear arc protection, certified AFL(R) 31.5 kA 1 s (according to IEC 62271-200).
  • Solid insulated busbar enables to extend or remove and insert a panel from the middle of the line-up without gas works on site.
  • Operator friendly: mimic diagram on panel front, no opening of doors required for manual operation.
  • Wide range of monitoring and diagnostic features for safe and reliable operations. All switching devices can be motor-operated and can be controlled remotely.


Other features

  • IEC61850 enabled supported by current and voltage sensor
  • Compared to ABB ZX0.2 gas-insulated switchgear, PrimeGear ZX0 uses less copper and has a shorter current path and lower resistance – generating 20% less heat and thermal losses.
