New compact latching relay for energy smart applications

Zettler has unveiled its new AZ 7621 P relay series. The latching power relay can switch 16A at 250VAC. Its electric life expectancy is 50K cycles operations at maximum ambient temperature of up to 85C. Efficient and compact, with low height of 15.7mm, standard frame as well as standard contact layout the power relay is designed for energy smart applications in a wide range of industries including industrial control, heating systems and building automation applications. The relays are available in two types – single and dual coil. At typical set/reset voltage the coil power range amounts to 196mW (single coil) or 294mW (dual coil) as well as 318mW (dual coil 24VDC). At nominal coil voltage set time as well as reset time is typically 10ms. Contact ratings for resistive loads are 4,000VA for maximum switched power, 16A for maximum switched current and 440VAC maximum switched voltage. A 5kV coil-contact dielectric strength and a 1kV dielectric strength between open contacts ensure that the AZ 7621 P is ro bust enough for even highly susceptible applications. It meets DIN VDE 0110 and IEC 60664-1 for basic insulation. Gold plated versions for contacts are optional. The terminals are tinned copper alloy, P. C. and the contact form is 1 form A (SPST-N.O.) or 1 form C (SPDT).
