Distribution Equipment Consumer Units

18th Ed. Consumer units:

Tested to meet the requirements of 536.4.201 - Icc 16kA / 230v as per BSEN 61439-3 Annex ZB. Refer to the installation instructions.

SPD Selection:

Where SPDs are required please refer to 534 4 8 and the SPD Manufacturer's installation instructions. Installing Type 1 SPDs in a consumer unit is difficult - see cabling requirements covered in 534.4.8 Et 10.

*Note : SPDs are passive devices and do not add to the heat rise in the enclosure i.e. they only take up space that has been assigned / tested with Doepke components in situ. Leave 0.5 module space between the SPD and adjacent components to prevent direct heat.

Consumer units accessories Technical data

  • Compact Metal Design
  • 30mA Type A RCCBs supplied as standard
  • 30mA Type A & F available to order
