ITALIANA RELE SERIES AT High Voltage Relays All-or-Nothing Relays specially designed for high voltage switching applications, having one or two changeover contacts rated 10A - 5KV AC1 - 5KVA. They are ideally suited for arduous duties where performance and reliability are at premium being capable of switching very high voltages. Featuring an open chassis design and 0.25” Faston terminals (6.3x0.8mm) secured to a ceramic base, to suit even extreme safety specifications.
