Type HVR10

Description

The HVR10 is a hybrid powerful high voltage relay in a compact design. It combines physical isolation of an electro-mechanical contact and state-of-the-art semi-conductor technology. The hybrid, arc-free switching system allows repeated and reliable disconnection, even in the event of an overload, of up to 2 megawatts – 2,000 A/1,000 V. The HVR10 withstands high short circuit currents up to 5,000 A until the fast HV-fuse trips. The compact unit can switch and permanently process 300 A up to 50,000 times, arc-free and wear-free. The innovative self-monitoring function immediately signals critical operating conditions to the controlgear.
