High‑Voltage DC Relay
CHPV-S450B
Ceramic brazed sealing design eliminates arc leakage risk to prevent fire and explosion.
The chamber is filled with hydrogen-based gas, which effectively inhibits contact oxidation and reduces arc ablation. It features low and stable contact resistance, and the contact part achieves IP67 protection rating.
Rated operating voltage: 1500VDC
2000A breaking capacity under abnormal working conditions
Non-polarized load
Overall dimension: 105.5 × 51 × 103 mm
Certification：
Application：
Energy Storage, EV Chargers
