LZ-N Relays

Coil data

  • Operating characteristics such as ‘Operate voltage’ and ‘Release voltage’ are influenced by mounting conditions, ambient temperature, etc.
    Therefore, please use the relay within ± 5% of rated coil voltage.
  • ‘Initial’ means the condition of products at the time of delivery.
