Fuse Switch Disconnector 3P 63A D02 400V

The Mersen 3P 63A D02 400V fuse switch disconnector is a modular device designed for direct mounting on a DIN rail. The device is used to isolate and protect electrical circuits against the effects of short circuits and overloads on the alternating current side. The component is used in three-phase photovoltaic installations, for example, when a 2-string PV combiner box is being installed. The 79 mm wide housing facilitates the proper arrangement of other protective equipment inside the control cabinet.

Key features

• Operation in circuits with voltages up to 400 V alternating current (AC) and a current capacity of 63 A.
• Short-circuit capacity of 50 kA allowing for safe circuit interruption during high fault currents.
• Integrated design for three poles, working with the popular D02 fuse link size.
• Rated impulse withstand voltage Uimp of 6 kV, protecting the system against the effects of transient overvoltages.
• Terminal mounts adapted for the safe connection of wires with a cross-section reaching 35 mm².
