Socket Boxes

Harju Elekter’s socket boxes are a practical solution for vehicle engine preheating and slow electric vehicle charging in residential parking areas, workplace car parks and public spaces. Designed for safe, straightforward everyday use, they provide convenient access to power where drivers need it most — without unnecessary complexity. Available with an affordable plastic enclosure or a premium aluminium housing, each socket box is built for dependable outdoor performance and long service life. The units are equipped with two 16 A Schuko outlets and integrated RCBO protection, supporting safe power delivery and added peace of mind for property owners and end users alike.
