About Us
Secure power supply
and energy distribution systems
LET Lüddecke Elektro Technik GmbH was founded in Ulm in 1973 by Walter Lüddecke. Today, more than 60 employees produce over 4000 custom-made control cabinets per year.
Our location is in the Ulm-Jungingen industrial park, conveniently situated between the B1O and A8 highways.
Our company specializes in the design and manufacture of low-voltage switchgear with rated currents up to 7400 A. Our competent and highly motivated team oversees the entire process, from planning and manufacturing to delivery.
As early as 1996, we were one of the first companies to receive type approval from the independent institute IPH Berlin according to German standard DIN EN 60439-1 VDE 0660 Part 5 and EC standard IEC 60439-1. Also since 1996, we have been ISO 9001 certified and are a franchise partner of various well-known manufacturers of switchgear systems.
Our customers include craft businesses, medium-sized companies, and large, internationally operating corporations. In our market segment, we have established ourselves as one of the most efficient companies on the market.
Our services include not only the construction of the switchgear but also the creation of the associated circuit diagrams and elevation drawings using CAD EPLAN P8 and EPLAN 5.70.
Skills

Charging infrastructure
as an outdoor or indoor distributor
States, regions, and companies worldwide are pursuing the path to climate neutrality at varying speeds. A key component of this is the shift away from the combustion engine towards electric vehicles, which are at least locally less emotionally impactful. Besides questions such as how to generate and store as much of the electrical energy as possible from renewable sources, or how to manufacture and transport battery cells in a climate-neutral way, the still-incomplete charging infrastructure poses the greatest threat to the rapid acceptance of this new technology by the general public.
Your charging solution, without expansion
Your house connection
With LET CHARGING, we deliver a
holistic charging infrastructure solution,
from the standard charging distributor for 16 wallboxes
from 22kW to the integrated overall system,
that at any time the maximum in the building
supplies available energy to the vehicles.
Manufacturer-neutral and virtually unlimitedly scalable.

Together we are strong. You've come to the right place!
In our view, a group of established companies will achieve disproportionate growth and success in the currently highly fragmented electrical engineering market. The group's companies will benefit disproportionately from joint activities and synergies – together, we can better overcome challenges such as recruitment, digitalization, and increasing complexity. Furthermore, we can consolidate purchasing and commercial activities, share best practices, and improve together. For this reason, we are building a strong, agile, entrepreneurial network with leading companies in German-speaking countries.
We want to cover all trades in electrical engineering, such as telecommunications construction, energy technology and distribution, building technology, network and data technology, security technology, control technology, automation.
The group of companies is consolidated under the E.GROUP name in each country.
Are you looking for a succession solution or are you an ambitious entrepreneur?
For this joint project, we are specifically seeking other established companies in the electrical engineering sector whose owners (if desired) and management, together with us—an entrepreneurial and financially strong partner—want to lay the foundation for the next growth phase of their company. Together, we aim to further expand your company's significant market position in this strategically attractive market.
