Panel Building And Industrial Control
Panel builders buy the parts that go inside the enclosure as much as the enclosure itself. Busbars, terminals and contactors decide whether a panel passes inspection and stays tight in service.
What Goes Wrong
- Terminals that loosen after thermal cycling and cause nuisance faults
- Busbar pitch and thickness that do not match the breaker range in stock
- Contactors sized for the wrong duty on frequently switched loads
- Enclosures without room to dress cable, so heat builds and installation takes longer
- Sourcing internal components from a different supplier than the enclosure
What This Buyer Needs
- Pin and fork type busbars across a usable current range
- Connecting terminals and brass neutral links for the neutral and earth bars
- Contactors specified for the control duty rather than the peak alone
- Enclosures with space for installation and heat dissipation
- Internal components and enclosures from the same order

- Assembling consumer units and distribution boards
- Motor control and power circuits using contactors
- Retrofitting a panel where the existing busbar pitch has to be matched
- Building panels for plant equipment, electric heaters and machine tools
- Producing panels in batches to a repeatable internal layout
From Enquiry To Delivery
Send the breaker range and internal layout you build to
We confirm which busbar widths and thicknesses fit and which terminals suit the conductor sizes
Sample sets go out so the first panel can be built and checked
Repeat orders hold the same specification so the layout does not have to change
What We Supply Into This Industry
- Pin type and fork type busbars in 32 A to 125 A reference currents
- Busbar thickness from 1.0 mm to 1.8 mm and widths of 5, 7 and 9 mm
- Connecting terminals, crimping lugs and brass neutral links
- AC contactors and enclosures in the same order

What busbar sizes are available?
The pin and fork type busbar is listed at reference currents of 32, 50, 63, 80, 100 and 125 A, in thicknesses of 1.0, 1.2, 1.4, 1.5, 1.7 and 1.8 mm and widths of 5, 7 and 9 mm.
What are the contactor ratings?
The listed AC contactor is a 3 pole unit rated 9 A, at 220/230 V, 380/400 V and 660/690 V, 50/60 Hz, and is stated to conform to IEC60947-4-1.
Can we buy the enclosure and the internal parts together?
Yes, and most panel builders do. Distribution boards, busbars, terminals and contactors all sit in the same range.
