Footnotes

  1. Complete the catalog number by adding the proper voltage code from Coil Voltage Codes for CA2K Control Relays (0.8–1.15 Uc) (0.85–1.10 Uc)—12 to 220/230 Vac 50/60 Hz, Coil Voltage Codes for CA2K Control Relays (0.8–1.15 Uc) (0.85–1.10 Uc)—230 to 660/690 Vac 50/60 Hz, Coil Voltage Codes for CA3K Control Relays (0.8–1.15 Uc)—12 to 72 Vdc, or Coil Voltage Codes for CA3K Control Relays (0.8–1.15 Uc)—100 to 250 Vdc. For example, CA2KN40G7.
  2. Complete the catalog number by adding the proper voltage code from Coil Voltage Codes for CA4K, Low Consumption Control Relays (Wide Range Coil: 0.7–1.3 Uc). For example, CA4KN40BW3 .
  3. Clip-on front mounting, 1 block per control relay.
  4. Auxiliary contact module not suitable for safety circuits.
  5. Not to be used on CA4KN relays.
  6. See “Clip-in Marker Strips” in Catalog 8501CT0101 for information on completing the catalog number.
  7. Protection by the limitation of the transient voltage to 2 Uc maximum. Maximum reduction of the transient voltage peaks. Slight time delay on drop-out (1.1 to 1.5 times normal).
  8. No overvoltage or oscillation frequency. Polarized component. Slight time delay on drop-out (1.1 to 1.5 times normal).
  9. Protection by limitation of the transient voltage to 3 Uc max. and limitation of the oscillation frequency. Slight time delay on drop-out (1.2 times to twice normal).
