Surge protective device type T1+T2, 2 poles, 600 V DC, Imax: 80kA, In: 25kA, Iimp: 12.5 kA (10/350) RSP-PV12.5-600-2P 2617385

Professional protection for photovoltaic installations

The surge protective device RSP-PV12.5-600-2P is an advanced I+II (T1+T2) class solution dedicated specifically to DC/PV installations. The device has been designed with photovoltaic networks in mind, providing comprehensive protection against atmospheric and switching surges. The plug-in design allows for quick mounting on a 35 mm DIN rail, which significantly simplifies installation in photovoltaic distribution boards.

MOV (Metal Oxide Varistor) technology is the heart of this surge protector, guaranteeing reliable absorption of surge energy. Thanks to its two-pole design, the device protects both conductors of the DC circuit, which is crucial for the safety of photovoltaic installations operating at a voltage of 600 V DC.

Technical parameters and performance

The device is characterized by impressive operating parameters. The rated discharge current In is 25 kA, allowing for safe operation in typical PV installations. The maximum discharge current Imax reaches 80 kA, providing a safety margin even during extreme atmospheric events.

The impulse current Iimp is exactly 12.5 kA with a 10/350 μs impulse characteristic, which corresponds to the standards for class I+II. The maximum continuous operating voltage is 600 V DC, ideally matched to most photovoltaic systems.

The protection level reaches 12.5 kV, guaranteeing effective protection against the strongest surges. The device occupies a standard width of 2 modules on the DIN rail, which facilitates distribution board planning.

Signaling and connection capabilities

The surge protector is equipped with an advanced fault signaling system. The optical signaling located on the device immediately informs about the need to replace the insert after it has been used during a surge.

Additionally, the device features potential-free contacts for remote fault signaling. This function enables integration with electrical installation monitoring systems and automatic service notification regarding the need for intervention.

The connection capabilities are very versatile - it supports single-core and multi-core rigid wires up to a cross-section of 35 mm², as well as flexible wires with ferrule ends up to 25 mm². This flexibility significantly simplifies the installation process in various types of distribution boards.

Compliance and certificates

The device meets the requirements of European standards and has the CN 8535400090 customs classification. The design complies with standards for the "Other" network type, making it a universal solution for diverse photovoltaic applications.

The product is non-disposable, which guarantees its multi-functional use after each operation - only the worn-out MOV inserts are replaced, while the housing itself remains functional throughout its entire service life.
