There are many product choices to help provide engineers more design flexibility, and are compatible with high-volume electronics assembly. These assist in meeting regulatory requirements and offer higher voltage ratings to allow use in new applications.

  • RGEF series for hold currents up to 14A
  • RHEF series for flatter thermal derating and operating temperatures up to 125°C
  • RUEF series for balance of voltage rating (30V) and hold current (up to 9A)
  • RUSBF series for fast time-to-trip and low-resistance computer applications
  • RXEF series for low hold currents (down to 50mA) and high voltage rating (up to 72V)
  • RKEF series for balance of voltage rating (60V) and hold current (up to 5A)


  • RoHS compliant
  • Halogen free (refers to: Br≤900ppm, Cl≤900ppm, Br+Cl≤1500ppm)
