◆ Product Overview
The FZN25-12D/630-20 indoor high-voltage load switch is a three-phase high-voltage switchgear rated at 12kV and 50Hz. It is designed for switching load currents, closed-loop currents, no-load transformer and cable substation currents, and short-circuit currents. This load switch, equipped with a grounding switch, is capable of withstanding short-circuit currents. Primarily employed in urban distribution substations and industrial power equipment with three-phase ring network terminal supply, it serves as a control and short-circuit protection device.
