Physical Characteristics

Lead Material 22 AWG Sn plated Cu (0.026in/0.65mm)
Insulating Material Cured, flame-retardant epoxy polymer, meets UL 94V-O requirements

Terms and Description

  1. Hold current (IH) : maximum current at which the device will not trip at 20℃
  2. Trip current (IT) : minimum current at which the device will always trip at 20℃ (2×IH)
  3. Typical power dissipation (Pd) :typical amount of power dissipation by the device when in tripped state in 20℃ still air environment
  4. Rmin : Minimum device resistance at 20℃ prior to tripping
  5. Rmax : Maximum device resistance at 20℃ prior to tripping
  6. R1 max : Maximum device resistance at 20℃ measured 1 hour post trip Imax. : Maximum interrupt current.
  7. Vmax interrup : Under specified conditions this is the highest voltage that can be applied to the device at the maximumcurrent. Devices have been designed to trip safely under higher power cross conditions, liketelecommunication standards(UL60950, GR1089 etc.), to assist equipment recognition in meeting theappropriate industry conditions.
  8. Vmax operating : For telecommunications devices this is the voltage we have used to obtain component recognition under UL1434.
