Description
Albright HV500F-21 – High Voltage Electromechanical DC Contactor
The Albright HV500F-21 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 24V 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 a PWM coil economiser. PWM manages the contactor coil and does not make the main contacts solid-state.
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.
Manufacturer reference: Albright HV500 product family.
