FAQ 

1.1788840000 Can the shell be directly installed on the control cabinet panel?

The

• It cannot be directly installed on the control cabinet panel. It is a cable side plug housing (cable connection cover), without panel mounting flanges and fixed holes. It is a cable end housing that matches the plug core.
• If it is to be fixed on the control cabinet door panel, a 04A specification panel mounting base (socket housing) must be selected. The base has flange holes and is used for screw locking to the cabinet panel.

Supported. The

• Power contacts (HA-4): Up to 4 power contacts (including 1 PE ground), each contact rated at 16A. This is the maximum power contact configuration for this enclosure.

The

• The shell body only has an internal M20×5 thread and does not come with a nut. The outer diameter of the cable is determined by the selected M20 cable nut.
