Founded in 1999, SchaltanlagenZubehör Bad Muskau GmbH (SZM) constantly strives to continue the long tradition of constructing switching devices in Bad Muskau as indirect successor of the former switching device plant (SGM). With the founding of SZM, a perfect mixture of experienced experts and young, committed employees succeeded in tailoring the development, production and servicing of circuit-breakers, switchgear and their accessories to the needs of today's world. One thing we are particularly proud of is our RETROFIT program, which offers more than 200 solutions for older switching technology (for example, for low-oil circuit-breakers of the product series SCI1, SCI4, SCIF, and vacuum circuit-breakers of the product series VCI, NVL and VL of past Muskau production). A state-of-the-art ERP-controlled production plant, CNC-controlled machine tools, design software that is always up to date and a comprehensive store of materials and spare parts ensure a high standard of certified quality and give our products their well-deserved, great reputation.
