E-T-A HVR10 High Voltage Relay

The Most Powerful High Voltage Relay up to 1000 V

The HVR10 is a hybrid and powerful high voltage relay in a compact design. It combines physical isolation of an electro-mechanical contact with the capabilities of ultramodern 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 high voltagefuse trips. The fist-sized unit can switch and permanently carry 300 A up to 100,000 times, arc-free and wear-free. The innovative self-monitoring function immediately signals critical operating conditions to the controlgear.

• Multiple disconnections even in critical conditions up to 2,000 A at 1,000 V.
• Enhanced protection of the on-board electrical system through integral fault detection and indication
• Minimum wear through arc-free switching
