The CHINT Ex9UEP DC Surge Arrestors (marketed as NOARK) are specifically designed to protect direct current (DC) electrical systems, particularly solar photovoltaic (PV) installations, from damaging voltage surges. Available in 2-pole and 3-pole configurations, these surge arrestors cater to different DC voltage requirements. The 2-pole models are designed for output voltages of 600V or 750V, with a nominal discharge current of 40kA, while the 3-pole versions handle 1200V with a 40kA nominal discharge current. These devices are crucial for diverting high-voltage spikes caused by lightning or switching events to ground, thus safeguarding valuable solar equipment such as inverters and panels. The Ex9UEP series ensures reliable protection in DC applications, contributing to the longevity and safety of solar power systems.
