Major Tech | ECCT450 Battery Powered Crimping and Cutting Tool 120kN | 400mm2 Copper Capacity
The Major Tech ECCT450 is a battery-powered hydraulic multitool that crimps and cuts, rated at 120kN. It crimps copper up to 400mm2 and aluminium up to 300mm2, and cuts cable up to 65mm diameter. The ECCT450 carries a 350 degree rotating crimping head and an OLED display for crimping time, battery charge, and fault codes. It ships as a kit with dies, interchangeable heads, two 18V 4.0Ah batteries, a charger, and a carry case.
Cable jointing at 400mm2 conventionally requires two separate tools and two trips back to the vehicle. The ECCT450 changes head rather than tool, since the crimping and cutting heads are interchangeable on a single 120kN body. A two-stage hydraulic system runs fast feed on approach, then transfers to power control at the crimp. Automatic retraction holds the ram until the crimp completes rather than releasing prematurely.
The 350 degree rotating head positions the die where the lug sits, which becomes significant in a pit or a congested cabinet. Quick motor stop halts the ram immediately, and the OLED display reports maintenance intervals rather than deferring them to a service schedule. Two 4.0Ah batteries and an optimised centre of gravity suit a full day of terminations.
Features
- 120kN rated pressure — the ECCT450 is rated at 120kN of hydraulic force at the head.
- Crimper and cutter in one body — heads are interchangeable, with quick changeover between crimping and cutting.
- 400mm2 copper capacity — crimps copper conductors to 400mm2 and aluminium conductors to 300mm2.
- 65mm cutting capacity — cuts copper and aluminium cable to 65mm diameter, and armoured cable to 50mm.
- 23mm stroke — the ram travels a 23mm stroke through each cycle.
- Twelve crimping dies supplied — dies from 16mm2 through to 400mm2 are included in the kit.
- 350 degree rotating head — the ECCT450 crimping head rotates 350 degrees for confined-space access.
- Two-stage hydraulic system — fast feed on approach, then power control as the die closes.
- OLED display — reports crimping time, battery charge, maintenance reminders, and fault codes.
- Automatic retraction — the ram retracts once the crimp completes, which prevents a partial cycle.
- Quick motor stop — the motor halts immediately, which Major Tech lists as an operator safety feature.
- Dies must match the termination — the ECCT450 die selection must suit the lug and conductor being crimped.
Where to use
- Cable jointing and terminations — the ECCT450 crimps lugs and ferrules across the full 16 to 400mm2 range.
- Switchboard and panel building — bench crimping of mains and submain terminations during assembly.
- Substation and industrial work — larger conductors where a 50kN tool has insufficient capacity.
- Solar and battery installations — DC cable terminations within the copper and aluminium range.
- Site work away from power — battery operation removes the need for a lead or a hydraulic hand pump.
- Mixed crimp and cut jobs — the ECCT450 changes head rather than requiring a second tool on the van.
The ECCT450 crimps copper to 400mm2 and aluminium to 300mm2, so larger conductors need a tool sized for them. Cutting is rated to 65mm cable diameter and 50mm armoured, which is a ceiling rather than a guide. A hydraulic tool at this rating develops substantial force at the head, so keep hands clear and work to the manufacturer's instructions.
