What MBS does
MBS AG & Co. KG is a German manufacturer of electrical measurement equipment headquartered in Sulzbach-Laufen, Baden-Württemberg, operating with approximately 170 employees and more than 40 years of operating history under a 'Made in Germany' positioning. The company designs and produces current transformers, voltage transformers, energy meters, Rogowski coils, residual current monitoring systems, shunts, measuring transducers, and bus bar insulators — spanning low-voltage products (ASR, ASK, WSK, EASR, EASK series), specialty power-quality CTs (XCTB up to 20 kHz, XKBR/XKBU split-core), miniature three-phase CTs (CTM 7, ASRD), flexible Rogowski coils (FASK), residual current monitoring (DACT with DACT-ISC and DACT-ELR peripherals), MPRO single- and three-phase MID-certified energy meters with M-Bus/Modbus/KNX/Wireless M-Bus/LAN communication modules, and medium-voltage CTs/VTs/sensors up to 30 kV. Approximately 98% of manufacturing is performed in-house, supported by a fully automated pallet warehouse with 600 spaces, and the firm operates a state-recognized testing facility (EBW 90) under ISO 9001:2015, with additional UL and MID certifications for international market access.
The company sells to commercial and industrial customers (Gewerbekunden), grid operators, municipal utilities, data center operators, panel builders, and system integrators across more than 40 countries through direct e-commerce for registered German accounts, enquiry-based international sales, and a network of distribution partners (e.g., DEIF in Denmark/Norway, Finn Electric in Finland, Polier Ingenierie in France). Product pricing is unit-based and publicly disclosed for select SKUs (single-phase AC meter from €69, three-phase direct meter €88, transformer meter €98), with non-standard and international configurations obtained through online enquiry.
Revenue mechanics are anchored in one-time product sales of hardware, complemented by recurring demand for replacement and expansion units within installed metering infrastructure. Strategic emphasis is placed on compliance with grid code requirements (e.g., VDE-AR-N 4100 harmonic monitoring), energy management per ISO 50001, and certified billing-grade measurement (MID).

MBS competitors and assessment
Company assessmentBroad incumbents
- Siemens: Diversified global incumbent in electrification, automation and digital industries, with overlapping LV/MV instrument transformers, energy meters and power quality offerings. Represents a broad-portfolio competitor rather than a niche specialist.
- ABB: Global electrical equipment and automation incumbent with a broad portfolio of instrument transformers, MV apparatus, energy meters and grid solutions. Competes with MBS at the high end of MV transformers and grid digitization while operating at vastly greater scale and scope.
- Schneider Electric: Global energy management and automation major with extensive current transformer, energy meter and power monitoring product lines. Overlaps with MBS in industrial energy management but serves a much broader customer and solution portfolio.
- Eaton: US-based power management major with significant LV/MV instrument transformer, metering and power quality offerings. Competes with MBS in data center, industrial and utility end markets through a broader electrical infrastructure portfolio.
