Albright HV500 – High Voltage Electromechanical DC ContactorThe Albright HV500 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 coil voltage depends on the exact ordered configuration.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 applicationsThis is a general HV500-series listing. Confirm the exact order code and coil voltage before selection.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.
Albright HV500AF-38 – Hermetically Sealed Electromechanical High-Voltage DC ContactorThe Albright HV500AF-38 is an electromechanical, single-pole normally-open (SPST-NO) high-voltage DC contactor in the HV500 series. It uses physical main power contacts to connect and disconnect DC circuits; it is not a solid-state relay. This configuration uses a 48V DC control coil with PWM coil economiser. The stated 48V DC is the control-coil voltage, not the main circuit voltage.Features
Electromechanical DC switching with normally-open main contacts
Hermetically sealed HV500 contactor construction
HV500 series validated for applications up to 1000V DC, subject to application-specific switching ratings
Thermal current rating up to 500A with appropriately sized conductors and installation conditions; switching ratings must be checked separately
Non-polarity-sensitive main contacts
PWM coil economiser
Typical applicationsDesigned for DC power switching in electric vehicle battery systems, charging equipment, renewable-energy systems, energy storage and industrial DC equipment, subject to electrical design and application verification.Selection note: Verify load voltage, continuous and breaking current, coil supply, pre-charge requirements and control options against the exact Albright catalogue and application requirements. PWM electronics are used for the coil circuit, not for solid-state switching of the main current. The HV500 contactor is not a substitute for appropriately rated external circuit protection.Technical reference: Albright HV500 manufacturer specifications.
Albright HV500F-21 – High Voltage Electromechanical DC ContactorThe 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 applicationsThe 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.
Albright HV500F-73S – High Voltage Electromechanical DC ContactorThe 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

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 applicationsThe 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.Manufacturer reference: Albright HV500 product family.
Albright HV500AF-47S – Hermetically Sealed Electromechanical High-Voltage DC ContactorThe Albright HV500AF-47S is an electromechanical, single-pole normally-open (SPST-NO) high-voltage DC contactor in the HV500 series. It uses physical main power contacts to connect and disconnect DC circuits; it is not a solid-state relay. This configuration uses a 24V DC control coil with PWM coil economiser and normally closed (NC) auxiliary contact. The stated 24V DC is the control-coil voltage, not the main circuit voltage.Features
