⚡ 1500V DC Ready
🛡️ Hydrogen Arc Extinguish
🚗 IATF 16949 Certified
Ceramic Sealed
HV DC Contactors
The definitive switching solution for EV Battery Packs (400V/800V) and Solar ESS (1500V). Featuring a hermetically sealed ceramic chamber for zero arc leakage.
Why Ceramic Brazing?
Unlike epoxy-sealed relays which can rupture under high pressure, our Ceramic Brazing Technology creates a molecular bond between the ceramic chamber and metal terminals.
- ✔ Hydrogen Filled: The chamber is filled with $H_2$ gas, which has high thermal conductivity to rapidly cool and extinguish arcs.
- ✔ Zero Oxidation: Contacts operate in an inert environment, ensuring stable resistance (< 0.2mΩ) over 20 years.
- ✔ Explosion Proof: Designed to withstand short-circuit currents up to 2000A without rupturing.
