        Major Tech | Non-Insulated Ratchet Crimping Tool 0.5mm² - 6mm² | Drop Forged Jaws

        The Major Tech CTR0333 is a ratchet crimping tool for non-insulated terminals, covering 0.5mm², 1.0mm², 2.5mm², 4.0mm², and 6.0mm² sizes. The CTR0333 is designed for automotive and white goods terminals, and measures 225mm long with a 35mm head and a 120mm handle. A ratchet mechanism with automatic release and manual override controls each cycle, and the jaws are drop forged.

        A hand-squeezed crimp is only as consistent as the operator's grip on the day. Under-compression produces a termination that survives inspection and fails a pull test months afterwards, frequently inside a vehicle loom where the fault is expensive to trace. The CTR0333 applies a ratchet mechanism that retains the jaws until the cycle completes, so every terminal receives identical compression. A manual override releases the jaws whenever a terminal sits misaligned and the crimp requires abandoning.

        One tool spanning five terminal sizes from 0.5mm² to 6.0mm² covers the range an auto electrician encounters across a working week. The drop forged jaws retain their profile through repeated cycles, which matters on a tool cycled hundreds of times per installation. At 225mm overall the CTR0333 still occupies a service kit rather than a bench, and automatic release removes any question about whether the crimp completed.

        Features

        • Ratchet mechanism — holds the jaws through the full cycle, so each terminal on the CTR0333 receives the same compression regardless of grip strength.
        • Automatic release — the jaws open once the crimp cycle completes, which removes the guesswork about whether the termination went home.
        • Manual override — releases the jaws mid-cycle where a terminal is misaligned and the crimp needs to be abandoned before completion.
        • Drop forged jaws — professional quality forged construction, which holds the crimp profile across repeated cycles.
        • Five terminal sizes — the CTR0333 crimps 0.5mm², 1.0mm², 2.5mm², 4.0mm², and 6.0mm² terminals from one set of jaws.
        • Non-insulated terminals — the jaws are profiled for non-insulated terminals, which is the constraint that sets this tool apart from an insulated crimper.
        • Automotive and white goods — designed for automotive and white goods terminals rather than switchboard or data terminations.
        • 225mm length — the overall length gives the mechanical advantage to close 6.0mm² terminals while still fitting a service kit.
        • 35mm head — the compact head works into the confined positions a vehicle loom presents.
        • 120mm handle — sized for a full-hand grip through the ratchet cycle.
        • Finger guard — a guard on the handle supports non-slip crimping through the cycle.

        Where to use

        • Automotive wiring repairs — the CTR0333 crimps non-insulated terminals on vehicle looms where a failed termination is expensive to chase.
        • Trailer wiring — terminates lighting and brake circuits on trailer harnesses, which sit in the size range the jaws cover.
        • Workshop electrical work — the CTR0333 suits a bench that turns over repeated terminations rather than the occasional crimp.
        • 12V accessory installations — terminates relays, switches, lights, and auxiliary circuits across the 0.5mm² to 6.0mm² band.
        • White goods service — designed for white goods terminals, so appliance repair work is inside the tool's intended scope.
        • Electrical service kits — at 225mm the tool travels in a maintenance and repair kit rather than living on a bench.

        The CTR0333 is profiled for non-insulated terminals only, so it is not the tool for pre-insulated terminals, bootlace ferrules, or coaxial connectors, all of which need their own jaw profile. Terminal capacity stops at 6.0mm², and larger lugs are outside the range the jaws will close on. Jaw profiles are not interchangeable on this tool.
