Cost-effective relays with 4.5 kV dielectric strength and 10 kV surge resistance
Munich, Germany, April 24th, 2017 – ZETTLER electronics, a manufacturer and distributor of electromagnetic and electronic components, introduces its new AZ SR131 series. The miniature power solar relays are capable of switching up to 35 A at 277 VAC. Coil voltages range from 5 up to 48 VDC. The relay is designed for the use in solar inverter applications according IEC 62109 but can be used in many other applications as well.
The dielectric strength is 4.5 kV between coil/contact. The relays are able to withstand 10 kV surge impulse. In the standard version the AZ SR131 has a contact gap of 1.8 mm and a dielectric strength of 2.5 kV between open contacts. A wide contact gap version (2.3 mm) is also available, with dielectric strength of 3.5 kV between open contacts.
The electric life expectancy is specified with 30,000 cycles at 35 A 277 VAC at an ambient temperature up to 85°C. The relays are available with silver tin oxide SPST-N.O. (1 Form A) contacts. Class F insulation (155° C) is standard.
The AZ SR131 power relays meet RoHS, REACH as well as IEC 61810-1 for the use in low voltage equipment and UL 508 for industrial control panels. Versions compliant to IEC-60335-1 (GWT-Glow Wire Testing) for household appliances are also available.
With UL and TÜV long life ratings, ZETTLER’s 35 AMP Miniature Power Relays are both cost-effective and high performance products. For a complete listing of ZETTLER“s power relay solutions please visit the website. For technical information and datasheets please contact ZETTLER electronics.
