Switch panels and panel construction

Switch panels

Switch panels literally form the link between the process control computer and the operating system. The switch panels are designed and built tailor-made in-house at Stolze. Because the panels are centralised, the process control computer's inputs and outputs can be integrated into the panels and a large part of the installation work can be carried out at Stolze's own workshop. This minimises the on-site assembly time required during system installation.

Distributors

The main distribution system constitutes the basis for the electrical system. The total lighting and power system is connected to the main distribution system through means of distributors. Stolze installs the cabling for the entire distribution system in accordance with the NEN 1010 or CSA/UL standards and directives.

UL/CSA Certification

Stolze is UL/CSA certified for the assembly of industrial control panels for US and Canada.

UL/CSA 508A certification is an industrial control panel directive, which is sought by electrical inspectors. The UL/CSA 508A Listing Mark on an industrial control panel provides evidence of third party certification to the municipal inspection authority and to the purchaser of the panel. A UL/CSA 508A Listing Mark shows that the panel complies with an acceptable safety standard.
The official definition of an industrial control panel, according to UL/CSA, is "an assembly incorporating two or more pieces of industrial control equipment or related control circuit devices, provided with interconnecting wiring and terminals for connections in the field. To allow the installer to properly install the panel in accordance to National Electrical Code (NEC) and other codes, electrical ratings and instructions are to be clearly explained on the panel."
Installation of a control panel can be completed in two ways: in an enclosure as "enclosed type" equipment, or arranged onto a mounting panel as "open type" equipment. For "open type" equipment, the assembly is installed in an enclosure provided by others, or at the installation site. Any of the outdoor enclosures or cabinets manufactured by Purcell Systems that carry the UL/CSA 508A Listing Mark would be classified as "enclosed type", and complies with the applicable requirements for outdoor panels noted in the UL/CSA 508A standard.
