The Sinotimer STPV-40.F four-pole DIN rail switch isolates and disconnects DC circuits in photovoltaic installations, allowing the power supply between the solar panels and the inverter to be switched off during maintenance or technical work. It is operated manually using ON/OFF positions and is designed for photovoltaic systems up to 1200 V DC, in both residential and industrial installations.
It installs quickly on a DIN rail and has a PA enclosure with a UL94V-0 flame-retardant rating. The contacts are made of copper with thick silver plating. Suitable for on-grid and off-grid photovoltaic systems, solar panel string isolation, and industrial DC applications.
