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).
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.
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.
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.
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.
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.
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.

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.
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.
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.
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.
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.
