Footnotes

  1. For additional terminal options, see Catalog MKTED210011EN. Check with local sales office for availability.
  2. Block of 4 contacts cannot be used with LP4K or LP5K contactors.
  3. Protection by limitation of the transient voltage to 2 Uc maximum. Maximum reduction of the transient voltage peaks. Slight time delay on drop-out (1.1–1.5 times normal).
  4. No overvoltage or oscillation frequency. Polarized component. Slight time delay on drop-out (1.1–1.5 times normal).
  5. Protection by limitation of the transient voltage to 3 Uc maximum and limitation of the oscillation frequency. Slight time delay on drop-out (1.2 times normal).
