PV string isolator 20A DC PKZ-SOL20 120938

PV string isolator – reliable protection for photovoltaic installations

This two-pole protective switch PKZ-SOL20 from Eaton is a key element of every photovoltaic installation. It provides effective protection against overloads and short circuits, guaranteeing safe and long-lasting operation of the entire system. The device is designed for mounting on a TH rail, which facilitates its integration with existing infrastructure.

Functionality and technical parameters

The switch is characterized by a rated current of 20A and is adapted to work in circuits with a voltage of up to 900V DC. It has an adjustable overload release range (14-20A) and short-circuit release (120A), allowing for precise adjustment to the specifics of the installation. The lack of a built-in undervoltage release and auxiliary contacts does not affect its basic function – ensuring the safety of the photovoltaic circuit. Made of high-quality materials, the PKZ-SOL20 switch ensures reliability and durability even in harsh operating conditions.

For installers and end users

The switch is easy and intuitive to install, thanks to the possibility of mounting on a TH or DIN rail. Its compact dimensions (58mm x 93mm x 76mm) allow for easy placement in a distribution box. For end users, this means peace of mind and confidence that their installation is properly protected against failures. For installers – convenient installation and confidence that they are offering their clients a high-quality product that meets all safety standards. This switch is an invaluable element in the system of protecting photovoltaic panels against the effects of short circuits, and the ability to set the release range allows for optimal adaptation to the actual short-circuit current of the installation.
