EVC 250 Compact High-Voltage Main Contactor

TE Connectivity's EVC 250 main contactor, a next generation product, has specifically been designed for use in hybrid, full-electric, and fuel cell vehicles. It is also used in vehicle charging systems and works without a pressurized contact chamber. 

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

This innovative design allows for compact dimensions of only 93 mm x 55.3 mm x 49.8 mm (3.7" x 2.2" x 2.0”). Due to the contactor’s simplified construction, with optimized parts, the EVC 250 can allow for a fully automated production.

The EVC 250 fulfills the insulation requirements of IEC 60664.
