VPU PV II 3 1000 surge protector 2530550000

Photovoltaic installation protection – reliability and safety

The VPU PV II 3 1000 surge protector is a key element protecting photovoltaic installations from the effects of overvoltages that can occur as a result of lightning strikes or rapid switching in the grid. It provides effective protection for installation components such as inverters, solar panels and cabling, minimizing the risk of failure and downtime. This is particularly important for systems connected to the grid, where overvoltages can be generated both from outside and from the power grid.

Construction and application

The device is based on Type II technology, which means it is designed to protect against the indirect effects of lightning strikes and overvoltages generated during normal operation of the installation. Mounting is done on a standard DIN TH-35 mm mounting rail, which facilitates integration with existing infrastructure. The protector is adapted to work in DC systems with a voltage of up to 1000V, making it compatible with most modern photovoltaic installations. Optical signaling of the operating status allows for quick identification of the need for replacement or intervention.

Key features and benefits

• High energy discharge capacity: Short-circuit current ISCPV at 11 kA guarantees effective protection even in the event of strong overvoltages.
• Versatility: Designed for operation in DC systems, ideal for photovoltaic installations.
• Compatibility: Supports wires with a cross-section of up to 35 mm² (stranded) and 25 mm² (flexible), ensuring wide compatibility with various types of cabling used in PV installations.
• Status indicator: Optical indication of operation facilitates diagnostics and quick response in the event of a failure.
• Durability: 5-year manufacturer's warranty demonstrates high quality workmanship and reliability.
• Modular design: Occupies only 3 modules on the DIN rail, saving space in the switchgear.
• Safety: Provides protection against overvoltages in accordance with applicable standards.

The VPU PV II 3 1000 surge protector is a solid solution for every installer and end user looking for reliable protection for their investment in solar energy.
