DC Disconnect Switch for Photovoltaic Installation 2P 30A DC P-SOL30 120935

The DC Disconnect Switch P-SOL30 is an open 2-pole switch designed for safely disconnecting the circuit between the photovoltaic generator and the inverter. The device supports a voltage of up to 1000 V DC and a nominal operating current in a typical configuration of 26 A (with a permissible current of up to 30 A when using the dedicated BK25/3 power terminal and appropriate cables). Thanks to its two-pole switching, it is also suitable for ungrounded systems, and its low internal resistance ensures minimal losses.

Manufacturer: Eaton (Moeller series). Eaton is an international company specializing in energy management and electrical equipment. Products from the P-SOL line are designed according to international standards (including IEC/EN 60947-3) and undergo durability testing, ensuring operational reliability in photovoltaic installations.
