Ordering / RFQ notes

  • Confirm exact ordering code, coil voltage, contact form and termination style before purchase.
  • Share load voltage/current, load type, duty cycle, ambient temperature and isolation requirement in RFQ.
  • Use the linked PDF datasheet for package drawing, dimensions and final rating limits.
  • For DC contactors, confirm carry current separately from make/break current, including voltage, load type, polarity, pre-charge and expected electrical life.
  • Follow the datasheet for coil suppression/economizer wiring; do not add external suppression if the model prohibits it.
  • Product family context: High Voltage DC Contactor.
Engineering selection notes

Avoid common specification mistakes

These notes keep product pages useful for engineers while avoiding overclaims. Final ratings remain model- and application-specific.

Carry current is not make/break currentContinuous current, making current and breaking current depend on DC voltage, time constant, polarity, pre-charge strategy and expected electrical life. Use the datasheet limits and RFQ review for the real load profile.
Pre-charge and polarity matterDC-link capacitors usually need a pre-charge path. Many DC contactors are polarity-sensitive for interruption, so bidirectional or reverse-current systems require explicit confirmation.
Follow coil suppression instructionsDo not add external flyback diodes or suppression to internally economized/suppressed contactor coils unless the contactor datasheet approves it; delayed release can reduce interrupt capability.

Typical applications

  • EV battery disconnect and pre-charge systems
  • Charging piles and DC fast charging
  • Energy storage systems
  • Industrial DC power and safety isolation

What to confirm before purchase

  • Voltage, current, load type and safety margin
  • Contact form, coil voltage and drive circuit
  • Mounting, wiring, environmental and compliance requirements
  • Sample validation quantity and production forecast
