EVC 250 Main Contactor (EVC 250)

EVC 250 Contactor

Safe contactors for brighter future mobility. Our EVC 250 main contactor is designed for use in hybrid, full-electric and fuel cell vehicles, on-board charging systems and works without pressurized contact chambers.

The EVC 250 contactor features larger contact gaps and optimized switching dynamics. It features high-performance arc suppressing magnets to effectively control the switching arc. The contactor achieves continuous current ratings of 250A, which ensures a safe short-circuit carry capability of 6,000A and complies with switching requirements in hybrid and electric vehicles. Service replacement due to pressure loss or gas leaking is no longer necessary.

Applications

  • Hybrid vehicles
  • Full battery electric vehicles, fuel-cell cars and
  • DC battery charging systems

Overview video featuring our next generation of contactors. TE's EVC 250 is a compact, high-voltage contactor used in hybrid, full-electric and fuel cell vehicles, on-board charging systems and works without pressurized contact chambers.

Requirements

The requirements for the main contactor under normal operation conditions are summarized here:

  • Connect and disconnect the battery
  • Carry several hundred Amps with low power dissipation
  • Ensure full galvanic isolation, when the vehicle is turned off
 
The requirements for failure cases are:

  • The contactor must be able to switch off overcurrents of up to 2,000A
  • The contactor must still be capable of separating the circuit after an overload
  • The contacts must remain closed in case of overload (especially at short circuits), as long as the contactor is activated
