ZETTLER Unveils High-Performance AZEV400 Relay for 3-Phase European EV Charging Applications

Posted on by

ZETTLER, the global market leader in AC switching for EVSE applications, proudly announces the launch of its latest innovation: the AZEV400 relay. Engineered specifically for the European 3-phase EV charging market, the AZEV400 sets a new benchmark for versatility, durability, and safety. The standard version features four normally open (NO) load contacts rated at 50A with integrated monitoring (mirror) contacts, in full compliance with IEC 60947-4-1 annex F.7.2 and IEC 61810-3 standards. With a robust 50A / 480 VAC switching capability, the AZEV400 is also adaptable as a relay for higher current 2-pole or 1-pole configurations.

Designed for IEC 61851 Mode 3 charging infrastructure, the AZEV400 is ideal for residential and commercial EVSE deployments across Europe. The relay supports ≥4.0 mm contact gap, a neutral pre-make design, and is rated for 50,000 cycles under CC2 conditions, ensuring long-term reliability. Additionally, the AZEV400 withstands inrush currents as per ISO 17409, and meets the demanding requirements of IEC 62955, IEC 62752, IEC 61008-1, and IEC 62052-11. With 5 kVRMS dielectric strength and 10 kV surge withstand voltage, ZETTLER’s latest relay is built for the future of safe, high-performance EV charging.

Product Spotlight, May 2019.

For the switching of 600VAC-800VAC circuits, large contactors have traditionally been the only viable option but new high capacity relays from ZETTLER are challenging those assumptions.
The new AZSR1160 and AZSR1180 PCB mount relays from ZETTLER provide system designers with a small form-factor alternative for switching power levels up to 165kVA. These new SPST relays can switch voltages up to 920VAC and currents up to 180A, all with a holding (coil) power of less than 0.5W. Contact gaps and insulation distances are optimized for commercial PV systems deployable up to 7000 m above sea level.
Key Features or Design Parameters include:

  • Specially designed terminals simplify thermal management and maximize lifetime
  • 3.6mm contact gap available
  • >10mm clearance/creapage
  • High surge breakdown voltage of 10kV
  • Coil voltage options from 6-48VDC
  • UL and TUV ratings
