PV installation surge protector DEHNguard MP YPV 1200 FM Type 2 942565

Photovoltaic system protection – reliability and safety

The DEHNguard MP YPV 1200 FM surge arrester is a multipolar modular device designed to protect photovoltaic installations from the effects of overvoltages. Using this arrester ensures safe and reliable operation of the PV system, minimizing the risk of damage caused by lightning strikes or other network disturbances. The design with a double connection terminal in "push-in" technology simplifies and speeds up installation, both in branched wiring and series connections.

Functionality and application

This type 2 arrester, compliant with EN 61643-31, is a key element of the surge protection system (SPD) in photovoltaic installations. It meets the requirements of IEC 60364-7-712 regarding special PV installations. The device protects against overvoltages both DC components (on the photovoltaic panel side) and AC components (on the inverter side). This protects not only the inverter itself, but also other system components such as cabling, protection devices and receiving equipment. High reliability is guaranteed by the use of a control and disconnecting device in "Thermo Dynamik Control" technology.

Key features and benefits

• High protection efficiency: Maximum discharge current of 40 kA and voltage protection level up to 4 kV provide effective protection against the effects of overvoltages.
• Status indication: Damage indicator and remote signaling contact inform about the need to replace the protective module, allowing for quick response and maintaining continuous protection.
• Easy installation: "Push-in" technology enables quick and easy connection of wires without the need for specialized tools.
• Modular design: Allows for easy replacement of protective modules after discharge, which reduces operating costs and extends the life of the device.
• Compliance with standards: Meeting the requirements of EN 61643-31 and IEC 60364-7-712 guarantees safety and compliance with applicable regulations.
• Short-circuit strength: Designed to operate in short-circuit conditions with a current of up to 10 kA (Iscpv).
• Rated voltage: Designed for installations with a maximum PV voltage of up to 1170 V DC.

The DEHNguard MP YPV 1200 FM surge arrester is an investment in the safety and long-term reliability of your photovoltaic installation. It provides not only protection against damage, but also peace of mind for the user and investor.
