Surge arrester RSP-PV4.5-1500-3P

Surge arrester RSP-PV4.5-1500-3P

Surge arrester for DC installations for DC/PV networks. Plug-in design Class I+II (T1+T2), number of poles 3. Rated voltage 1500 V DC. Rated discharge current In 20KA, max discharge current 50KA, peak current Iimp 4.5 kA 10/350. MOV technology with potential-free contact for remote fault indication.

The RSP-PV4.5-1500-3P is a Class I+II three-pole surge arrester designed for comprehensive protection of photovoltaic installations operating at up to 1500 V DC, including primarily solar farms and their infrastructure. The device provides a high level of safety and operational reliability even in the most demanding environmental conditions. It is the ideal solution for designers, installers and investors looking for proven and durable protection for DC solar systems.

 

Main features and benefits of PV surge arresters up to 1500 V DC:

  • Multi-stage protection (Class I+II): allows discharge currents and switching overvoltages to be safely dissipated without risk of damaging installation components.
  • Maximum DC operating voltage: 1500 V - compliance with the latest standards for large PV installations.
  • Three-pole design (2 x operating pole + PE) - dedicated to DC systems, protecting in differential and common mode.
  • Short-circuit resistance up to 1 kA - allows operation in demanding conditions with a high risk of short circuits.
  • Compact DIN rail-mounted housing - quick installation in standard DC switchgear.
  • High durability and reliability of components - suitable for long-term operation in outdoor and industrial environments.
  • MOV protection: two individual protection modules individually even in the event of failure of one module.

 

Application and installation recommendations: 

The RSP-PV4.5-1500-3P arrester should be installed in parallel on DC networks, allowing protection in both common and different modes. It is recommended to mount the device both on the solar panel side and at the inverter, especially if the DC line is long or routed outside. This effectively protects the installation against surges from lightning or electrical interference.
