About Hülsbömer & Weischer
Hülsbömer & Weischer GmbH is an electrical company founded in 1913 in Münster with core business areas in switchgear assembly, electrical installation and photovoltaics. In switchgear assembly, the company manufactures low-voltage distribution boards of all kinds, including insulating material, sheet steel, floor-standing, wall-mounted, meter, cable and terminal distribution boards, from a single-family home to a football stadium. The entire value chain is kept in-house: switchgear planning and design, metalworking with custom-made control cabinet housings, busbar systems and copper connections, wiring, assembly, as well as mechanical and electrical final inspection in the company's own testing field. Materials used are sheet steel, copper and insulating materials; only tested components from selected suppliers are installed. The delivery area covers the Münsterland, the region from the North Sea to the Lower Rhine, and from Hanover to the Dutch border. Since summer 2023, the company has additionally offered consulting, planning and installation of photovoltaic systems; the electrical machine construction department was closed as of 31.08.2023. The administrative headquarters is at Coermühle 2B, while production takes place on Sprakeler Straße in Münster-Kinderhaus.
