Protection for industrial low and medium voltage networks

For industrial MV/LV installations SYMAP^® solutions cover protection, control, metering, interlocking, communication and diagnostics in switchgear, process drives and energy centres. Typical functions include protection of feeder cells, motors, transformers, auxiliary supplies, cable connections, DC systems, and integration with SCADA/DCS systems.

SYMAP^® Compact+ is considered as a compact Protection & Control IED for individual cells, particularly when protection, breaker control, metering, signalling, communication and local logic are required in a single device. The classic SYMAP^® series is considered for more complex industrial architectures, larger signal counts, retrofit projects, dedicated application variants, system coordination or integration into a wider protection/PMS system.

Typical applications

Recommended products

SYMAP^® Compact+ — compact IED for individual industrial cells

Classic SYMAP^® series — application variants for more complex industrial systems

Note: Compact+ F1/F2/F3/F4 should not be interpreted as direct equivalents of the classic SYMAP^® F/M/T/G variants. The Compact+ variant is selected according to measurement inputs, CT/VT configuration, I/O, communication and Order Code options. The classic SYMAP^® series is selected according to the application and system architecture.

Which SYMAP^® for this application?

For individual industrial MV/LV cells, SYMAP^® Compact+ is most often considered, because it combines protection, control, metering, interlocking, signalling and communication in a single IED. Compact+ F1/F2/F3/F4 variants are selected according to CT/VT measurements, earth-fault regime, number of voltage systems, I/O signals, communication and Order Code options. The classic SYMAP^® series is considered for more complex industrial architectures, larger signal counts, retrofit projects, or where dedicated application variants such as F, M, T, LD, DC or ARC are required. SYMAP^® D is not listed as a general industrial function, but only where a specific industrial network has a line/connection that requires distance protection 21.
