Subminiature HVAC relay is VDE-approved

11 February 2004 Switches, Relays & Keypads

American Zetller's AZ770 relay is available in SPST (N.O.) and SPDT configurations. This relay has a 5 A, 250 V a.c., 100 000 cycle UL and now the VDE rating comes standard with Class B insulation. Due to its 8 mm creepage distance, it has an extremely high dielectric strength of 5000 V r.m.s. and a 10 kV surge withstand from contact to coil. The AZ770 has a sensitive coil (only 200 mW) and is available with gold plated contacts and an epoxy sealed cover. The relay is suitable for HVAC applications where lightning induced surges are a problem. Now with VDE approval, the AZ770 is suited for both European and US control applications.
