Fast response and environmental resistance - features of a modern surge arrester
Each surge arrester of the RSP-EH series from Relpol is distinguished by a very short response time (<25 ns), high resistance to adverse environmental conditions and easy mounting on a standard DIN rail. The use of spark-gap technology ensures effective surge suppression while maintaining long device life.
Arrester compliant with EN 61643-11 - a guarantee of safety
The RSP-EH high-voltage surge arrester from Relpol complies with the EN 61643-11:2011 standard, which confirms its high efficiency in surge protection. Thanks to its compliance with current safety standards, this surge arrester is used in switchgears, transformer stations, industrial power supply systems and critical infrastructure facilities where reliability of protection is crucial.
RSP-EH surge arrester - protection even if a module is damaged
The RSP-EH series surge arrester ensures that the system continues to operate even if one module is damaged. Each arrester has two MOV modules operating in parallel per pole and two independent status indicators, allowing the unit to continue operating if one module fails. This solution increases the reliability of the protection and extends the safe operating time.
Reliable arrester for critical applications
With redundant operation and a design based on high-performance components, Relpol's RSP-EH surge arrester is the ideal solution for systems that require continuity of operation and resistance to extreme surge conditions. It is the perfect choice for projects where safety and durability cannot be compromised.
