Logstrup is a Danish modular low-voltage switchboard platform engineered to IEC 61439-1/2. CWS is the New Zealand panel-builder constructing Logstrup-based switchboards for plants that need a globally type-tested platform, built and supported locally from our Invercargill factory. We hold a licensed panel-builder relationship with A/S Løgstrup-Steel and assemble the kit into finished boards inside the type-tested envelope.
Logstrup is a modular low-voltage switchboard platform manufactured by A/S Løgstrup-Steel, a Danish family-owned company founded in 1958 and still led by the Løgstrup family. The platform is type-tested as a complete system to IEC 61439-1/2 (the parent standard for AS/NZS 61439) and is deployed worldwide through licensed panel-builders. CWS builds Logstrup boards in Invercargill inside that type-tested envelope.
Every Logstrup section is built on a 190 mm modular grid. The framework is 2 mm Aluzinc steel in a five-bend construction, heavier and more rigid than the bent-tray frames used in lower-tier systems. That rigidity is what lets Logstrup carry main busbars up to 8,500 A and pass internal arc tests at fault levels most NZ plants will never see.
The single biggest reason consultants specify Logstrup is the type-test envelope. The platform is independently verified by certified European laboratories and carries full design verification documentation under IEC 61439-1/2, the parent standard for our local AS/NZS 61439. Every Logstrup board we build in Invercargill inherits that type-test envelope and ships with the routine-test report under AS/NZS 61439.
Specifying a Simotrol switchboard or MCC for a NZ industrial project? We build Simotrol assemblies in our ISO 9001-certified Invercargill workshop, designed and verified to AS/NZS 61439, with the full compliance documentation pack delivered with every job.
Logstrup is one of the few platforms where Form 4b (full separation including separated terminals between functional units) is built into the type-test report, not retrofitted with sheet-metal separators. Our standard Logstrup build for NZ projects is Form 4a, which matches the Simotrol default and the majority of NZ consultant specifications. Form 4b is a documented option whenever the consultant or asset owner specifies it.
The advantage of a Logstrup board built by CWS is that you get the global type-test envelope of a Danish-engineered platform together with the lead time, FAT and after-sales support of a local panel-builder. The kit ships from Denmark; the board is engineered, assembled, wired, tested, delivered and supported from our Invercargill factory. If something needs attention five years from now, you call our Invercargill workshop, not an offshore aftercare desk.
