Description and application These AC zero crossing relay, ZCR16A_1A, contains handouk electronic’s metal contact-protection function, so life time is several times longer than normal relay and its surge on state current at start mode is around 170A, and switching noise at start and switching mode is ultimately limited in switching mode. This is well suitable for high stressing load which is applied to relay at the starting mode or every switching cycles.
