The LTMC 803U-3-C is an 800 kN CNC 3-in-1 busbar processing center that punches, shears and bends copper and aluminum busbar in a single footprint for Canadian switchgear, transformer and busway shops. It handles busbar up to 20 mm thick by 250 mm wide and punches holes from 4.3 to 34 mm diameter, so it covers heavy feeder and transformer connections without a separate press. The bending station holds ±1° accuracy with ±0.5° repeatability, and three independent hydraulic systems let punch, shear and bend run at once to shorten lead time. At 2100 kg with a 1950×1560×1450 mm envelope it fits a fabricator's floor while staying serviceable through standard LJMC tooling and dies.
803U-3-C — Nominal force: 800 kN. Test condition: three independent hydraulic units driving punch, shear and bend stations on copper/aluminum busbar. Result: 800 kN rated force, the top of the 303U/503U/803U-3-C family. Baseline: 303U-3-C at 300 kN and 503U-3-C at 500 kN (same aid 14 spec table), so the 803U-3-C delivers 2.7× the force of the 303U-3-C for thicker feeder busbar.
803U-3-C — Maximum busbar size: 20 mm thick × 250 mm wide. Test condition: single copper or aluminum bar fed to punch, shear and bend units. Result: processes up to 20 mm thickness and 250 mm width. Baseline: 303U-3-C handles 12×150 mm and 503U-3-C 16×200 mm (same aid 14 table); the 803U-3-C adds 4 mm thickness and 50 mm width over the 503U-3-C for larger transformer links.
803U-3-C — Punching diameter range: 4.3–34 mm. Test condition: six-mode integral turret punching round and oblong holes. Result: holes from 4.3 mm to 34 mm diameter. Baseline: 303U-3-C 4.3–25 mm and 503U-3-C 4.3–30 mm (same aid 14 table); the 34 mm top end suits bolted connector patterns common on Canadian switchgear busbar.
803U-3-C — Bending precision: ±1° (repeat ±0.5°). Test condition: horizontal and vertical bending on the closed bending station. Result: ±1° bend angle with ±0.5° repeatability across production runs. Baseline: identical to 303U-3-C and 503U-3-C in the same family table, so angle consistency is matched by the lighter models at lower force.
803U-3-C — Power and weight: 3×5.5 kW, 2100 kg. Test condition: three-pump hydraulic drive, shop 600 V/60 Hz via transformer. Result: 16.5 kW total installed, 2100 kg footprint. Baseline: 503U-3-C at 3×5.5 kW / 1700 kg and 303U-3-C at 3×4 kW / 1400 kg (same aid 14 table); the 803U-3-C is the heaviest of the three for its 800 kN rating.
The machine uses a three-pump hydraulic drive rated at 3×5.5 kW, which a Canadian shop feeds through a step-down or isolation transformer from its 600 V, 60 Hz service. Confirm the exact supply and plug configuration with our team for your province.
LTMC supplies the 803U-3-C for busbar that goes into switchgear and busduct assemblies built to CSA C22.2 in Canada (UL in the US). Tell us what your AHJ review asks for on components, wiring and documentation and we will match the build to it.
Delivery and customs clearance depend on your port and order configuration, so confirm the current lead time and Incoterms with our team. We pack in waterproof film and wooden cases for overseas transit to Canadian fabricators.
Product Description

This series of CNC busbar processing machine has three processing units: punching, shearing/cutting and bending. The three unit can be used simultaneously or sequentially, which shortens the processing time and improves production efficiency. The bending unit adopts Siemens PLC of Germany.
