TE Connectivity announces new compact plug-in contactor for high-voltage applications

TE Connectivity has announced its new EVC 80 for hybrid and electric vehicles. The EVC 80’s crucial feature is its relatively low maximum amperage of 80 A, which allows it to be used as either a main or auxiliary contactor. Its compact design also features improved heat dissipation, and allows it to be used in higher-efficiency battery-disconnect unit (BDU) setups.

The EVC 80 has a voltage rating of up to 450 V, and measures 50 by 40 by 37 mm.  The small size and the non-polarity-sensitive design are quite intentional: TE intends the contactor to be used in tight mounting spaces and difficult installation scenarios. Also, its outer core is shielded to lessen interference with other devices.

Key features:

  • Hermetically sealed with nitrogen
  • 450 VDC Voltage Rating
  • Continuous current up to 80 A at -40° to 85° C
  • 50 g shock rated in several orientations (energized)
  • Dielectric withstand voltage of 2,920 VDC per 1 mA of leakage current
  • Insulation resistance greater than 1 GΩ at 500 V

“As hybrid and electric vehicles continue to gain momentum, we see a growing demand in the market for a lower amperage, compact conductor,” says TE Automotive Product Manager Terrance Blackmon. “This is our first plug-in contactor, and it boasts the lowest amperage of any of our product offerings, previously held by our EVC 135 contactor.”
