The DC isolation disconnect switch is an electrical safety device used, among other things, to manually disconnect PV panels for installation, repair or maintenance. It has a locking device in the off position. Constructed of silver alloy with low resistivity, good conductivity, and resistance to high temperature and oxidation. Connectors made of galvanised copper. Can be mounted in a switch box.
Ideal for photovoltaic professionals and amateurs
The DC circuit breaker from Qoltec, also known as an isolating disconnect switch, acts as a so-called main circuit breaker. It prevents short circuits, overloads and damage to the installation. It is used to safely disconnect the power supply and reconnect the DC circuits, i.e. to disconnect PV modules from the inverter, for example, or to stop the inverter in the event of a fault, or to isolate the circuit when carrying out work in switchgear.
Switch lock function
The product has an ON/OFF switch and a LOCK locking device, which effectively prevents the installation from being accidentally switched on. The switch can be placed in a switchboard on a TH-35 rail or surface-mounted with screws.
Safe photovoltaic installation
Every photovoltaic installation works on direct current, so it is important to ensure that its operation is fault-free and safe. To guarantee reliable operation and adequate protection, the installation should be equipped with a photovoltaic DC isolator, a so-called DC circuit breaker. This is usually installed between the photovoltaic panels and the solar inverter to isolate the PV panels during any maintenance work, for example. This makes it safe to carry out any repairs, replacements of damaged plant components or system extensions.
