New electromechanical relay series shows best-in-class performance ratings for applications in appliance, lighting, controls and similar industries
The ZETTLER electronics GmbH, a manufacturer and distributor of electromagnetic and electronic components, introduces its new AZ 576 relay series. Designed for applications in the appliance, lighting, controls and similar industries, the miniature power relay meets the ever increasing demands for more power, more cycles and higher ambient temperatures.
Establishing best-in-class standards in terms of UL performance the 20 A power relay solution performs at 277 VAC at an ambient temperature up to 85° C (185° F) with ratings of 20 A for 30 k cycles. At 105° C (221° F) it has ratings of 17 A for 100 k cycles (1 Form A) as well as for 30 k cycles (1 Form C). Coil voltages range from 3 to 110 VDC. At nominal coil voltage operate time is typically less than 8 ms with release time of typically less than 4 ms. Pin spacing is an industry-standard (5.0 mm). General purpose, pilot duty, HP, inductive, and TV loads round out the top UL ratings. A 5kV coil-contact dielectric strength and a 10kV surge resistance ensure that the AZ576 is robust enough for even highly susceptible applications.

Class F insulation (155° C / 311° F) is standard. Additionally, the relay is available in an epoxy sealed version allowing reliable usage in demanding environments. Its low height of 16.2 mm and its standard frame as well as the standard contact layout qualifies the relay for use in different applications for a number of industries, including industry electronics, home and HVAC appliances and vending machines.
With the AZ 576 Zettler provides cost-efficient alternatives to its already existing monostable relay series AZ 762 and AZ 764. For a complete listing of Zettler’s power relay solutions please visit the website. For technical information and datasheets please contact ZETTLER electronics GmbH.
