With zero-voltage crossing technology, ELR 1/25-240 and ELR 1/35-600 single-phase electronic load relays are for ac load switching applications where low maintenance and high reliability are required. In addition to producing no high-frequency transients, the relays are also said to offer silent switching and to have an integral heatsink and practically unlimited mechanical life. Applications include production machines, temperature controllers, conveyor equipment, and lighting systems.
