• EntelliGuard G low-voltage power circuit breaker (Switchgear) — ABB EntelliGuard G power breakers, 400-6,000 A GE-heritage frames with parts still fully available
• HV/EHV power transformer legacy class (69-765 kV) (Transformer) — ABB-brand HV and EHV power transformers, 69-765 kV transmission class, a legacy fleet that trades brokered and off-market
• MegaFlex DPA (UPS) — ABB's megawatt-class modular UPS, extended to 2,000 kW in March 2026 and the only ABB line trading used
• SACE Emax 2 air circuit breaker (E1.2-E6.2) (Switchgear) — ABB SACE Emax 2 air circuit breakers to 6,300 A and 200 kA, current-sold alongside the 2025 Emax 3 successor
• SafePlus compact gas-insulated switchgear (Switchgear) — ABB SafePlus compact switchgear, sealed-tank secondary distribution to 40.5 kV with an SF6-free Air variant
• SafeRing Air ring main unit (Switchgear) — ABB SafeRing Air, the dry-air SF6-free ring main unit that superseded the fluoroketone AirPlus variant.
• UniGear Digital (Switchgear) — ABB UniGear Digital, the sensor and IEC 61850 option set that turns UniGear panels into digital switchgear
• UniGear ZS1 air-insulated switchgear (Switchgear) — ABB UniGear ZS1 metal-clad switchgear to 24 kV, 4,000 A, and 63 kA, the IEC primary-distribution flagship
• UniGear ZS2 36 kV air-insulated switchgear (Switchgear) — ABB UniGear ZS2, the 36 kV metal-clad line whose class carries the longest switchgear lead times of all
• ZX0 gas-insulated switchgear (Switchgear) — ABB ZX0 block-design SF6 switchgear, the legacy line whose successor PrimeGear ZX0 ships SF6-free at 12 kV
• ZX1.2 gas-insulated switchgear (Switchgear) — ABB ZX1.2 single-busbar SF6 switchgear to 36 kV, a legacy line now off the current ZX portfolio
