Surge protector type T2, 2-pole, 1000 V DC, Imax: 40kA, In: 20kA (8/20) RSP-T2-DC/2P 2617146

DC Installation Protection with Surge Arresters

The surge arrester RSP-T2-DC/2P is a key element in protecting direct current (DC) installations, especially in photovoltaic systems. This Class T2, two-pole device is designed to protect against the effects of atmospheric and switching surges. Its task is to minimize the risk of damage to sensitive electronic components in the installation, ensuring continuity and reliable operation.

Construction and Application

The arrester's construction is based on technology that allows for a quick response to sudden voltage increases. The nominal discharge current In of 20kA (8/20) and the maximum discharge current Imax of 40kA guarantee effective protection even in the event of strong impulses. The maximum continuous operating voltage Uc of 1000V DC makes it an ideal solution for photovoltaic installations of various powers. Mounting is done on a standard 35 mm DIN rail, which simplifies integration with existing electrical infrastructure.

Advantages and Benefits

• Effective protection: Protects against damage caused by surges, extending the life of equipment.
• Two-pole design: Provides comprehensive protection in the DC circuit.
• High efficiency: In and Imax nominal currents guarantee efficient operation in various conditions.
• Easy installation: Standard mounting on a 35 mm DIN rail simplifies installation and servicing.
• Optical signaling: A built-in optical indicator informs about the operation of the arrester, facilitating diagnostics and problem location.
• Compliance with standards: Has a CE marking, confirming compliance with European safety standards.
• Wide range of operating voltages: Possibility of use in installations with a voltage of up to 1000V DC (depending on the configuration).

This arrester is used not only in photovoltaic installations, but also wherever there is a risk of surges in DC circuits – e.g. in emergency power systems, electric vehicle chargers or industrial controllers. Thanks to its reliability and ease of use, it is an optimal solution for both professional installers and end users who care about the safety of their devices. The manufacturer is Relpol S.A., known for its high-quality electrical components.
