A three-pole knife disconnect switch for low-voltage AC circuits, rated 380 V at 50 Hz with current options of 100 A, 200 A, 400 A, 800 A and 1600 A. It uses a phenolic resin insulating base with high-conductivity copper contacts, an insulated manual lever and a full visible contact break for safe isolation. Typical duties include main disconnection in industrial distribution panels, motor control centres and commercial power boards. Confirm the pole count, the current rating and the panel or base mounting arrangement before ordering.Key details:Materials: Phenolic resin base; high-conductivity copper contacts (silver-plated optional)
