Surge protective device type T1+T2, 3 poles, 1500 V DC, Imax: 50kA, In: 20kA, Iimp: 4.5 kA (10/350) RSP-PV4.5-1500-3P 2617384

Professional protection for photovoltaic installations

The RSP-PV4.5-1500-3P surge protective device is an advanced T1+T2 class solution designed for DC/PV networks. The device utilizes MOV technology with potential-free contacts, providing effective surge protection in photovoltaic systems with a rated voltage of 1500 V DC.

The plug-in design in a 3-module size allows for easy mounting on a standard 35 mm DIN rail, making it an ideal solution for both new installations and the modernization of existing PV systems.

Operating parameters and performance

The device is characterized by high current parameters: the rated discharge current In is 20 kA, and the maximum discharge current reaches 50 kA. The peak impulse current Iimp 4.5 kA (10/350) guarantees effective protection even during very strong lightning strikes.

A high protection level of 4.5 kV ensures comprehensive protection against harmful surges. The 3-pole design allows for efficient discharge of impulse energy through all phase conductors.

Signaling and status monitoring

The surge protector is equipped with optical signaling, which immediately informs about the device's status. Additionally, it features potential-free contacts for remote fault signaling, enabling integration with building monitoring systems or home automation.

This allows the user to continuously monitor the protection status and react quickly to any damage to the surge protector components.

Application and compatibility

The device is intended for DC/PV networks, making it an ideal solution for photovoltaic farms as well as PV installations on the roofs of residential and commercial buildings. The design supports single-core and multi-core conductors up to a cross-section of 35 mm², as well as flexible conductors up to a cross-section of 25 mm².

Mounting on a DIN rail ensures versatility of application in electrical switchboards from various manufacturers. The device meets the requirements of European standards and can be used in installations requiring the highest safety standards.
