Description
Albright HV500F-73S – High Voltage Electromechanical DC Contactor
The Albright HV500F-73S is a hermetically sealed electromechanical DC contactor in the HV500 family, designed to switch DC power using physical main contacts. It is not a solid-state relay. The listed 48V DC refers to the control-coil voltage, not the voltage switched by the main contacts.
Key features
- Electromechanical switching with normally open (NO) main contacts
- Hermetically sealed high-voltage DC contactor design
- HV500 family specifications include high-voltage operation up to 1000V DC, subject to application-dependent ratings
- High-current switching for properly engineered DC circuits; verify continuous, making and breaking ratings for the specific operating conditions
Configuration and applications
The product listing identifies an intermittent-duty configuration; verify coil operating limits and duty cycle with the manufacturer's part-specific documentation.
Typical application areas include electric vehicles, battery packs, DC charging, renewable energy, energy storage and industrial DC distribution, where the part's voltage and current capabilities meet system requirements.
Engineering note: HV500 contactors do not replace external fuses, circuit breakers, or suitable pre-charge arrangements. Verify current and voltage under load, coil supply, operating duty, auxiliary contacts, mounting and environmental requirements for the exact model.
