LV Switchboards
LV Switchboards
Low-voltage power control centres (PCCs) and motor control centres (MCCs) engineered to IEC 61439, with form-segregation up to Form 4b and short-circuit ratings to suit the system fault level.
Engineered to IEC 61439
Designs validated against IEC 61439 for assembly verification, including temperature rise, short-circuit withstand, dielectric, mechanical operation, IP protection and impact tests. Build verified by routine inspection and tests on every panel before despatch.
Siemens 8PU SIVACON licensed builds
As a Siemens Licensed Partner, Symatic manufactures the 8PU SIVACON LV switchboard family in drawout (withdrawable) and fixed executions, with type-tested kits and Siemens-supplied incoming and outgoing devices.
Form segregation & safety
Form-2 to Form-4b segregation between busbars, functional units and cable terminations. Plug-in / withdrawable feeders for fast feeder replacement and safer maintenance. IP31 / IP41 / IP54 enclosure classes available.
- Drawout, plug-in and fixed executions
- Form 4b segregation as required by spec
- Hinged door modules with door interlocks
- Cable / busduct top or bottom entry
Motor control centres
Intelligent and conventional MCCs for industrial process plants — DOL, star-delta, soft-starter and VFD outgoing modules with overload, short-circuit and earth-fault protection coordinated to IEC 60947 device curves.
