Qoltec DC isolator with locking function 1200V 32A 8kV

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.
