American Zettler AZSR & AZEV Series Relays for Automotive Applications

Reliable switching solutions for high-power automotive systems. American Zettler’s AZSR & AZEV relays offer precision, durability, and safety for EV charging, energy storage, and high-voltage control applications.

  • High Switching Capacity: AZSR250 handles up to 50A, while AZEV400 delivers 80A per contact pair—perfect for demanding EV and automotive applications.
  • Automotive-Grade Durability: Both series are rated for extended electrical life with reinforced insulation and contact reliability under high-load conditions.
  • EV-Ready Performance: AZEV400 is designed for IEC 61851 Mode 3 and SAE J1772 Level 2 charging—ideal for AC EVSE and onboard charging systems.
  • Safety First: Wide contact gaps (≥1.85mm AZSR, ≥4.0mm AZEV) and dielectric strength up to 5kVrms ensure dependable isolation and reduced arc risk.
  • Space-Efficient & Robust: Compact form factors with sealed enclosures, PBT housings, and THT terminals—ready for tough automotive environments.
  • Built-in Monitoring Options: AZEV400 features an integrated SPST-NC monitor contact for real-time status diagnostics in safety-critical EV circuits.
