PV string isolator 12A DC PKZ-SOL12 120937

Photovoltaic installation protection – reliable DC string isolator

The PV PKZ-SOL12 string isolator is a key element protecting photovoltaic installations from the effects of short circuits and overloads. Designed to operate at voltages up to 900V DC, it provides effective protection for solar panels and the entire system. The device is mounted on a TH rail and is characterized by a compact design, making it easy to install even in limited spaces.

Features and application

The PKZ-SOL12 isolator is intended for protecting DC circuits in photovoltaic systems. Its task is to quickly disconnect the circuit in the event of a dangerous short-circuit or overload current being detected, minimizing the risk of damage to components and fire. Thanks to the adjustable overload release range (8-12A) and short-circuit release (72A), it can be precisely adapted to the characteristics of the protected installation. The design with a knob allows for convenient manual control, which is particularly useful during servicing and maintenance of the system.

Advantages for installers and users

• Safety: Provides effective protection against short circuits and overloads, protecting the investment in the photovoltaic system.
