PV surge protector 2P (T2 DC) 1000VDC BY7-40/2-1000 87.745

Photovoltaic installation protection – reliable surge arrester

This two-pole surge arrester BY7-40/2-1000, designed for DC photovoltaic systems, is a key element ensuring the safety and long-term operation of your installation. Its task is to protect against the effects of surges, both those caused by lightning strikes and switching disturbances in the grid. Mounting on a TH35 rail is simple and intuitive – the device takes up only 36 mm wide (2 modules 18mm), making it easy to integrate with existing infrastructure.

Key parameters and application

The BY7-40/2-1000 surge arrester is characterized by high parameters, confirmed by a declaration of conformity with CE standards. Maximum current (Imax) at 40kA and rated current (In) of 20kA guarantee effective protection even in the event of strong surges. Rated voltage (Uc) 1000VDC makes it an ideal solution for most photovoltaic installations, and protection voltage (Up) of 4kV minimizes the risk of damage to connected devices. Thanks to protection class T2 (C), this arrester reacts quickly to sudden voltage changes, protecting sensitive PV system components.

Safety and reliability in practice

• Effective protection: Protects photovoltaic modules and other elements of the installation from damage caused by surges.
• Easy installation: Quick and easy mounting on a standard TH35 rail – saving time and installation costs.
• Compact dimensions: Takes up minimal space in the switchgear, making it easier to integrate with existing infrastructure.
• Compliance with standards: The CE declaration confirms compliance with applicable safety standards.
• Durable construction: Ensures long-lasting and reliable operation in demanding operating conditions.
• Suitable for professionals and end users: Both installers and installation owners will appreciate its ease of use and effectiveness.

The BY7-40/2-1000 surge arrester is an investment in the safety of your photovoltaic installation, which will help you avoid costly repairs and downtime in the future. By choosing this product, you gain confidence in reliable protection against the effects of surges.
