Product Details
Technical Drawing & Mounting Dimensions
Standard mounting footprint with two M5 mounting hardware (2.5–3.0 Nm torque) and a range of female terminal choices (M6 / M8 / M10) so the same contactor can be drop-in fitted into battery packs, motor controllers and DC distribution boxes. Overall dimensions 81 x 71 x 62 mm (3.17 x 2.81 x 2.44 in).
Why Choose Albright HV500AF-172?
High Voltage, High Current Capacity
Rated for 1000 V D.C. continuous operation with up to 500 A continuous current (350 MCM busbars) and 250 A continuous on 50 mm² cables, delivering reliable high-voltage DC switching for traction, energy storage and DC fast-charging applications.
Hermetically Sealed — Exceeds IP67
Contacts, auxiliary and PWM circuit are hermetically sealed — exceeding IP67 — so the contactor is safe to operate in wet, dusty and outdoor environments, including direct exposure to rain, road splash and salt fog.
Wide Coil Voltage Range (12–96 V D.C.)
One contactor covers 12 V, 24 V, 36 V, 48 V, 60 V, 72 V and 96 V D.C. coil systems, eliminating the need to stock multiple variants and simplifying integration across 12 V, 24 V and 48 V automotive, AGV and traction platforms.
Configurable Auxiliary Contacts
Auxiliary contact block offers SPST-NO, SPST-NC and SPST-NC mirror configurations for status monitoring and interlocking with the BMS, motor controller or charging-pile controller — no extra wiring harness required.
Low Power Loss (<30 mV at 100 A)
Typical voltage drop is less than 30 mV at 100 A, minimizing heat dissipation and improving overall system efficiency in battery-powered applications where every watt matters.
Built for Harsh Environments
Operates from -45°C to +85°C, withstands 20 G shock and 20 G vibration (80–2000 Hz) and tolerates 5%–85% humidity — ideal for off-road EVs, forklifts, AGVs and energy storage systems in extreme climates.
Product Applications
Industrial Vehicles Electric forklifts, electric pallet trucks, electric aerial work platforms, intelligent logistics systems, automated guided vehicles (AGV), cold chain logistics equipment, industrial robots, electric tools, and electric golf carts. | DC Charging Equipment Chargers, small DC charging piles, monoblock DC charging piles, split-type DC charging piles (group charging), ultra-fast DC charging piles, and integrated DC charging piles for heavy-duty trucks. |
Energy Storage System Large-scale energy storage (generation-side, grid-side), medium-scale energy storage (industrial & commercial), small-scale energy storage (residential), and photovoltaic solar energy systems. | Frequency Conversion Equipment High-voltage frequency converters, power conversion systems (PCS), industrial rectifier power supplies, motor drives, and UPS systems. |
Frequently Asked Questions
Q1: What is the rated voltage and current of the HV500AF-172?
A: The HV500AF-172 is rated for 12 V – 1000 V D.C. contact voltage and 500 A continuous current (with 350 MCM busbars) / 250 A continuous on 50 mm² cables, suitable for traction, ESS and DC fast-charging systems.
Q2: What coil voltage range does the HV500AF-172 support?
A: The HV500AF-172 covers a wide 12 V D.C. – 96 V D.C. coil voltage range, including common 12 V, 24 V, 36 V, 48 V, 60 V, 72 V and 96 V systems. Specify the exact coil voltage when requesting a quote.
Q3: What auxiliary contact options are available?
A: The auxiliary block is configurable as SPST-NO, SPST-NC or SPST-NC mirror, mechanically linked to the main contacts for BMS / controller status feedback and interlock logic.
Q4: Is the HV500AF-172 sealed for outdoor use?
A: Yes. The contacts, auxiliary and PWM circuit are hermetically sealed and exceed IP67, making the contactor safe for outdoor, wet and high-humidity environments.
Q5: What terminal options does the HV500AF-172 offer?
A: Three female terminal sizes are available — M6 (3.0–4.5 Nm), M8 (8.0–9.5 Nm) and M10 (15.0–18.0 Nm) — so the contactor can drop-in replace Albright / GIGAVAC-style units of the same footprint.
Q6: How do I request a quote and what is the lead time?
A: Submit your required specifications (current rating, coil voltage, auxiliary contact type, terminal size, and quantity) through the inquiry form or contact us via WhatsApp. Our engineers will respond within 24 hours. Sample lead time is [to verify with factory].
