DC Contactor EVK500

500A High Voltage DC Contactor Product Introduction

The 500A high voltage DC contactor is a key circuit control device for ultra-high power DC systems. It supports a wide voltage operating range of DC 12V to 1500V and provides 12V/24V/48V coil versions with a coil power of 6~6.5W. This model is designed for high current switch control needs in energy storage, transportation, power electronic equipment and other fields. It adopts advanced magnetic blow-out technology and high-performance silver contact materials to ensure excellent disconnection ability and low contact ablation rate under high voltage and high current.

The shell adopts high-strength engineering plastics and fully sealed design, with excellent protection, shockproof and corrosion resistance. Its built-in auxiliary contact function (optional) can feedback the contact status in real time to realize remote monitoring and system automation linkage. A variety of installation methods and terminal types are suitable for different project requirements and have high integration flexibility.
