| Advantage | Benefit for Your Application |
|---|---|
| ✅ Up to 1000V DC Switching | Rated contact voltage 12~1000V DC covers high-voltage battery packs, EV powertrains and DC distribution circuits on a single contactor platform. |
| ✅ 250A Continuous / 500A Max | 250A continuous with 50mm2 (1-1/0 AWG) cable terminations, and up to 500A with 190mm2 (350 MCM) busbars - size the connection to the load. |
| ✅ Fully Sealed - Exceeds IP67 | Main contacts, auxiliary contacts and the PWM coil circuit are hermetically sealed - dust, water splash and condensation never reach the switching elements. |
| ✅ PWM Coil Drive, 12~96V Window | The built-in PWM economizer holds coil power down after pick-up and accepts a wide 12~96V DC coil supply (units pictured: 24V PWM) - tolerant of saggy vehicle supplies. |
| ✅ Ruggedized for Mobile Duty | 20G shock (1/2 sine, 11ms) and 20G vibration 80-2000Hz endurance, -45~+85°C operating window and 3000m altitude rating for forklifts, AGVs and construction machinery. |
| ✅ Flexible Feedback Options | Choose SPST-NO, SPST-NC or SPST-NC mirror auxiliary contacts for weld detection, interlocking and contactor status feedback in series strings. |

Q1. What is the difference between the 250A and 500A ratings?
A: Both refer to continuous current - 250A with 50mm2 (1-1/0 AWG) cable terminations, or up to 500A when using 190mm2 (350 MCM) busbars. Size your terminations to the load and follow the torque values on the dimension drawing.
Q2. What coil voltage does the HV500AF-23 use?
A: The coil accepts a 12~96V DC supply window under PWM control; the units pictured are marked 24V PWM. The built-in PWM economizer reduces holding power after pick-up, so a wide supply tolerance is acceptable.
Q3. What exactly does "full-sealed, exceeds IP67" cover?
A: The main contacts, auxiliary contacts and the PWM coil circuit are hermetically sealed from the environment - dust, water splash and condensation cannot reach the switching elements, making the contactor suitable for harsh vehicle and outdoor cabinet environments.
Q4. Are auxiliary contacts available?
A: Yes - SPST-NO, SPST-NC or SPST-NC mirror configurations. They are typically used for weld detection, interlocking and contactor status feedback; auxiliary leads are 280mm long as standard.
Q5. How does HV500AF-23 differ from HV500F-121?
A: Both share the HV500 platform and core electrical ratings (12~1000V DC, 250A/500A, PWM coil). The -23 suffix on the AF variant denotes its coil/auxiliary configuration - check which auxiliary contact type your control system needs, or contact us for a selection table.
Q6. What are the mounting and termination requirements?
A: Per the HV500 dimension drawing: M8 main terminals tightened to 8.0-9.5Nm, M5 mounting hardware to 2.5-3.0Nm (M6/M8 female terminals 3.0-4.5Nm / 8.0-9.5Nm, M10 male terminals 15.0-18.0Nm on relevant variants), Ø60mm base circle, approx. 400g overall weight.
