Major Tech 0.5mm²–6.0mm² Ratchet Crimping Tool (CTR0333)

Heavy-Duty Ratcheting Crimper for Pre-Insulated Terminals

Engineered for precision and reliability, the Major Tech CTR0333 Crimping Tool delivers gas-tight, high-integrity crimps on pre-insulated electrical terminals ranging from 0.5mm² to 6.0mm². Built for electricians, switchboard builders, and field technicians, this tool features color-coded crimp nests designed to streamline workflow and prevent terminal misapplication.

The full-cycle ratchet mechanism guarantees that every crimp completes fully before releasing, eliminating loose or under-crimped connections. Featuring an adjustable pressure wheel to maintain tension accuracy over time, alongside an emergency manual override, the CTR0323 ensures safe, repeatable performance on every job site.

Key Features

• Wide Terminal Range: Accommodates standard pre-insulated terminals across 3 color-coded nests: Red (0.5–1.5mm²), Blue (1.5–2.5mm²), and Yellow (4.0–6.0mm²).

• Full-Cycle Ratchet Operation: Holds jaws locked until a complete, factory-standard crimp is applied.

• Adjustable Tension Wheel: Fine-tune crimp pressure to account for long-term wear or varying terminal sleeve thicknesses.

• Automatic Release & Safety Override: Jaws release automatically at cycle completion, with a manual lever to clear jams or misalignments safely.

• Drop-Forged Jaws: Heavy-duty carbon steel head provides long-lasting edge alignment and structural integrity.

• Ergonomic Cushion Grips: High-leverage handles feature non-slip rubber covers to minimize operator fatigue during repetitive work.
