What Goes Into a Custom MCC

From single DOL feeders through to multi-module starter lineups, we wire the motor control logic your process needs.

  • Soft-start modules with Schneider, ABB or Allen-Bradley soft-starters where the application calls for it
  • VSD supply feeders out of the MCC, with Schneider Altivar, ABB ACS or Allen-Bradley PowerFlex drives housed in dedicated drive cabinets or wall-mounted enclosures we can build alongside
  • Schneider, ABB, Allen-Bradley or Siemens motor protection circuit breakers and contactors as specified
  • Door-mounted local-off-remote selector switches, manual start and stop pushbuttons, thermistor reset, run and trip indication, ammeters and PLC interface relays
  • Profibus, Modbus TCP, EtherNet/IP and Modbus RTU communications to your control system
  • Schneider PLC integration with Modicon M340 and M580 process controllers, paired with X80 I/O modules
  • Marshalling cubicles, IO terminals, and intrinsically safe barriers where the application calls for it

Buyer FAQ: Motor Control Centres

Common questions from engineers and contractors specifying MCCs in NZ.

Form 2, Form 3 or Form 4 — which one do we need?

It depends on how much of the board you need to keep live while maintaining a single starter. Form 2 separates busbars from functional units. Form 3 also separates terminals between units. Form 4 fully separates busbars, functional units and terminals. Most dairy and freezing works MCCs in NZ are Form 4b. See our guide on forms of segregation for a longer explanation.

Are starter modules demountable or withdrawable?

Demountable as standard. Modules are bolted in place and unbolt for replacement or maintenance after the section is isolated. The Logstrup platform offers a fully withdrawable option, available on request where the application calls for racking out under load.

How long does a custom MCC take?

Typical lead time is 8 to 14 weeks from sign-off to factory acceptance test, depending on size, platform, and component availability. Long-lead items like large ACBs and specialist VSDs drive the front of the schedule. See our full lead-time guide for what shifts the timeline.

Do you handle communications and PLC integration?

Yes. We wire and commission Profibus, Modbus TCP, EtherNet/IP and Modbus RTU to your PLC system. For Schneider PLC integration we routinely build with Modicon M340 and M580 process controllers, paired with X80 I/O modules and Advantys distributed I/O blocks. AS-Interface and parallel-wired safety modules supported on request. PLC hardware itself is usually housed in a separate control cubicle either attached to the MCC or remote-mounted, we can build that cubicle too. See our automation and control page for PLC and SCADA work.

What standards do your MCCs comply with?

AS/NZS 61439 for the assembly itself, AS/NZS 3000 for the installation work, AS/NZS 3008 for cable sizing. Type-test backing comes through Simotrol and Logstrup platforms. We can supply full FAT documentation and test certificates with the board.
