PV installation surge protector DEHNguard MP YPV 1500 FM Type 2 942567

Photovoltaic system protection – reliability and safety

The DEHNguard MP YPV 1500 FM surge arrester is a multipolar modular device designed to effectively protect photovoltaic installations from the effects of overvoltage. Its construction based on replaceable protective modules ensures easy maintenance and replacement of elements if necessary. This keeps the installation safe and ready for operation for a long time. The device complies with EN 61643-31, which confirms its high quality and effectiveness.

Construction and application

This type 2 surge arrester is designed for mounting in photovoltaic installation switchboards. It has a double connection terminal in "push-in" technology, which simplifies and speeds up the process of connecting branched wires and series connections. The width of the device is 3 modules, which allows it to be easily placed even in limited space. Use in PV installations is in accordance with the requirements of IEC 60364-7-712: 2002-05, concerning special photovoltaic installations.

Key features and benefits

• High reliability: The device is equipped with a control and disconnecting device with "Thermo Dynamik Control" technology, which ensures reliable operation and indicates damage to the protective module.
• Status indication: It has a damage indicator and a remote signaling contact, enabling quick identification of problems and service response.
• Protection parameters: Provides protection up to a maximum PV voltage of 1500 V DC, and its ability to withstand short-circuit currents Iscpv is 10 kA. The maximum discharge current is as high as 40 kA, and the voltage protection level is ≤ 5 kV.
• Versatility: Suitable for both branched wiring and series connections, increasing installation flexibility.
• Safety: Protects the circuit against overload and short circuit - like most circuit breakers in this class.
• Modular construction: Allows for quick replacement of damaged elements without the need to disassemble the entire housing.
• Compliance with standards: Meets the requirements of EN 61643-31 and IEC 60364-7-712, guaranteeing safety and compliance with regulations.

This surge arrester is a solid solution for every installer and end user who values the safety and reliability of the photovoltaic system.
