• What does DPST-N/C mean?
  DPST-N/C stands for Double Pole Single Throw – Normally Closed. This means both poles remain closed until the coil is energized, allowing current to pass through by default.
• Is this relay rated for electronic ballasts or LED drivers?
  No. The RIB01P30-NC is not rated for electronic loads such as LED drivers or electronic ballasts. Use only with rated resistive or inductive loads.
• How do I order different contact combinations?
  Add “-NONC” to the model number to get one pole normally open and one normally closed.

• Tip: Use the -NC configuration when you need fail-safe circuits that default to “closed” when unpowered.
• Tip: Always verify control wiring per the datasheet when using alternate contact configurations like -NC or -NONC.
• Mistake to Avoid: This relay is not intended for switching LED or electronic ballast loads. Use a rated model for those applications.
