Terminals, mounting rails and drainage inside a box
- Junction boxThis term
The box contains the specified connections and accessories. Check the complete installed enclosure and electrical duties.
- Terminal block
The block provides defined conductor connections. Confirm circuit function, wire range, preparation and clamping method.
- DIN rail
The profile supports compatible devices. Mounting on a rail does not automatically make an electrical or protective-earth connection.
- Drain plug
The outlet manages accumulated liquid through its specified function. Check the lowest-point orientation and retained ingress duty.
An enclosure contains electrical connections, supports terminals and controls entry and drainage paths. Component ratings do not by themselves establish the rating of the complete assembly.
Conceptual internal arrangements, not a wiring diagram. Circuit functions, conductor preparation, clearances, bonding and drainage orientation require the actual design.
