Why is it worth entrusting us with prefabrication?
The most common-and most expensive-issues we see in client facilities:
-
overheating contacts and connections → increased fire risk, short circuits, and failures under full load
-
loose terminals, poor shielding, or inadequate ventilation → corrosion, EMC interference, nuisance alarms, and damaged controllers
-
missing shock protection and improper PE continuity → risk of accidents during operation and maintenance
-
non-compliance with standards → problems during inspections and conformity checks, gaps in documentation, risk of administrative action, and production stoppages
-
lack of an EU Declaration of Conformity for the complete assembly (not just individual components) → issues with insurance, audits, and exports
At Manserw, we eliminate these risks from the start. We build in accordance with PN-EN 61439 (including full design and routine verification), provide an EU Declaration of Conformity for the complete cabinet, and perform thermal imaging tests under load to detect hotspots before failures occur. We also ensure alignment with the Machinery Directive 2006/42/EC and IEC 61131-3 where applicable.
Prefabrication of Control Cabinets and Industrial Switchgear
Manserw offers comprehensive services in the design, prefabrication, and installation of control cabinets and low-voltage switchgear. Our projects are characterized by engineering precision, aesthetic execution, and full compliance with applicable standards, including PN-EN 61439.
Standards and Certification
We implement projects in accordance with European market requirements (CE) and, at the client's request, to American market standards (UL 508A). Each cabinet comes with a complete set of as-built documentation, electrical schematics, and a EU Declaration of Conformity.
Our production process
EPLAN Analysis and Design:
We work with the provided documentation or create our own projects in the CAE environment (WS-CAD). We verify the selection of equipment in terms of the thermal balance of the cabinet.
01.
Component Selection:
As an official partner of Schneider Electric and distributor of Wenglor, we guarantee the originality of components and the availability of spare parts. We use proven solutions from brands like Schneider, Eaton, Rittal, and Siemens.
02.
Precise Assembly and Wiring:
-
We use professional labeling systems (wires, devices, terminal blocks) according to the schematic, which reduces service time by 70%.
-
We ensure electromagnetic compatibility (EMC) through the separation of signal and power paths – crucial for inverters.
-
We crimp end sleeves with professional crimping tools.
03.
Tests and Measurements:
Each cabinet undergoes functional tests ("cold" and under voltage), insulation resistance measurements, and continuity tests of protective conductors before shipping.

Scope of Implementation
Control cabinets for machines and technological lines
We design and build "turnkey" control cabinets for machines and production lines – PLC, HMI, wiring, testing, and documentation.
Control pulpits and HMI operator panels
We build ergonomic control desks and integrated HMI panels – design, assembly, programming of screens, and functional testing.
Server and telecommunication cabinets in industrial execution
We manufacture server and telecommunication cabinets for harsh industrial conditions – ventilation, security, structured cabling.
Modernization of existing distribution boards (replacement of equipment)
We are modernizing old switchgear – replacing contactors, fuses, meters, and controllers. We increase reliability without replacing the entire cabinet.
