Circuit breaker must meet IEC-898, UL-1077, VDE-0641 or CSA22.2-
No.235. ABB S271 breaker with ‘K’ trip curve meets the requirement.
Note:
• Current limit is to be 15A maximum
4.13.2 Protective ground
4.13.3 AC input wiring details to KCM
• KCM AC input terminals are: L1, L2, N-neutral, G-ground/PE
• For 115 VAC inputs, connect the hot wire to “L1” as it is fused.
Connect the neutral wire to “N”
• For 2 phase (220-240VAC applications in the US) connect the first
leg to “L1” and the second leg to “L2” which is also fused
▲ Each KCM must have its own power mains disconnect or circuit
breaker.
▲ The disconnecting means or circuit breaker must be in close
proximity to the equipment and within easy reach of the operator.
▲ The disconnecting means or circuit breaker must be labeled as the
disconnecting device for the connected equipment.
▲ There must be no power consuming components electrically
connected between the supply mains and the disconnecting
