New Energy Relay RL81A-150 (ROC) 150A 750VDC support Custom R&D
New Energy HV DC Relay 150A 750VDC — R&D Engineered for the Electric Future
Magnetic Arc Extinguishing · 4000V Withstand · Non-Polar Load · Custom R&D Partner
???? Built for the New Energy Era — Your R&D Partner for HV DC Switching
This RL81A type high-voltage DC relay is purpose-built for new energy applications — EV charging stations, battery energy storage systems (BESS), solar inverters, and DC microgrids. With magnetic arc extinguishing for safe 750VDC cut-off, 4000V+ isolation, and non-polar load connection, it handles bidirectional current flow with exceptional surge tolerance. Our R&D team goes further: we customize current ratings, coil configurations, auxiliary contacts, and packaging to integrate seamlessly into your EV/ESS product architecture — while optimizing cost at the system level.
