Surge protective device type T1+T2, 3 poles, 1000 V DC, Imax: 80kA, In: 25kA, Iimp: 8 kA (10/350) RSP-PV12.5-1000-3P 2617386

Professional protection for photovoltaic installations DC

The surge protective device RSP-PV12.5-1000-3P is an advanced T1+T2 class solution designed specifically for photovoltaic installations operating in DC/PV systems. The device provides comprehensive surge protection in a three-pole configuration, protecting photovoltaic panels and inverters from damage caused by lightning strikes and other network disturbances.

The plug-in design allows for quick mounting on a standard 35 mm DIN rail, occupying only 3 modules in the distribution board. The device supports solid and stranded conductors with a cross-section up to 35 mm², as well as flexible conductors with ferrules up to 25 mm², ensuring flexibility during installation.

Electrical parameters and performance

Model RSP-PV12.5-1000-3P operates at a rated voltage of 1000 V DC, making it ideal for larger photovoltaic installations. The rated discharge current In = 25 kA guarantees effective protection during normal network disturbances, while the maximum discharge current Imax = 80 kA ensures safety even during extreme surges.

The impulse current Iimp = 12.5 kA (10/350) has been specifically selected to match the characteristics of lightning discharges, providing optimal protection against direct lightning strikes. The protection level of 12.5 kV effectively limits the impulse voltage to a level safe for the connected electronics.

MOV technology and status signaling

The device utilizes modern MOV (Metal Oxide Varistor) technology, which is characterized by a fast response time and high reliability. The built-in potential-free contact enables the connection of a remote fault signaling system, allowing for device status monitoring from an alarm control panel or a building management system.

Compliance and operating conditions

The surge arrester meets the requirements of the Type 1+2 protection class, confirming its effectiveness against both direct lightning strikes (T1) and induced disturbances (T2). The device is intended for use in DC/PV type network systems and can be used in various photovoltaic installation configurations.

The modular design allows for easy replacement of worn components without the need to dismantle the entire installation. All technical parameters comply with current European standards, guaranteeing safety of use and reliable operation for many years of service.
