UKGD-800F22K 800A DC1500V Parallel-Pole Switch Disconnector for Large-Scale Energy Storage Systems
The UKGD-800F22K reaches 800A at DC1500V using a parallel-pole capacity-boosting design (4 poles internally paralleled to function as 2 poles), improving current-carrying capacity and heat dissipation compared to a standard 2-pole build.
It carries CE certification and is intended for high-current main disconnects in large PV plants, grid-scale storage, and heavy industrial DC systems where compact footprint and strong thermal performance both matter.
