Power cable cutter and crimper Rittal 4050.456 — for 0.5–2.5 mm² cables, AC 100–240 V, 50/60 Hz, 5.5 bar

Rittal 4050.456 is an electropneumatic power cable cutter and crimper designed for precise cutting, stripping and crimping of conductor sections from 0.5 to 2.5 mm². The device combines mains electrical drive (AC 100–240 V, 50/60 Hz) with pneumatic actuation at 5.5 bar to deliver consistent, repeatable crimps. It features a five-way magazine for processing insulated wire end ferrules from reels, making it suitable for electrical workshops and production environments where throughput and uniform quality are required.

Advantages

The tool provides stable, repeatable crimps and clean cuts for small to medium cross-section cables through coordinated electropneumatic operation. Its five-way magazine accepts ferrules on reels and reduces manual handling, increasing processing speed and minimizing feeding errors. Compact design and straightforward controls simplify integration into workshop benches or production cells while the extended mains voltage range ensures compatibility with common power supplies in different regions.

Suitable for

• Cutting, stripping and crimping insulated wire end ferrules with conductor cross-sections 0.5–2.5 mm²
• Electrical workshops performing recurring wire termination tasks
• Small to medium production lines requiring consistent crimp quality and higher throughput
• Workstations using reel-fed ferrules to reduce manual loading time

When it may not be suitable

This unit is intended for conductor sizes within the 0.5–2.5 mm² range; it is not suitable for very fine wires below 0.5 mm² or larger power cables above 2.5 mm². If your application requires fully manual operation without any pneumatic supply or if you cannot provide the specified 5.5 bar air pressure, this electropneumatic model will not operate as intended.

Key specifications

• Conductor cross-section range: 0.5–2.5 mm²
• Power input: AC 100–240 V, 50/60 Hz
• Required pneumatic pressure: 5.5 bar
• Feeding system: 5-way magazine for reel-fed insulated ferrules
• Functionality: cutting, stripping and crimping of insulated ferrules
• Operation type: electropneumatic

How to use

Install the unit on a stable bench and connect to the mains supply within the specified voltage range. Connect a clean, regulated compressed air source set to approximately 5.5 bar. Load the reel-fed ferrules into the five-way magazine according to the supplier instructions and set the desired conductor cross-section if an adjustment is required. Feed stripped conductors into the crimping position or use the integrated strip/cut features as intended. Activate the cycle using the control switch or foot pedal where available; the electropneumatic mechanism will perform cutting and crimping in a single sequence. Verify crimp quality periodically and adjust settings or perform maintenance as recommended by the manufacturer.

What to consider before purchase

• Confirm your conductor sizes fall within 0.5–2.5 mm²
• Ensure availability of AC mains in the 100–240 V range and compatible frequency (50/60 Hz)
• Verify a reliable compressed air supply able to deliver around 5.5 bar
• Check compatibility of ferrule types and reel formats with the five-way magazine
• Plan for periodic inspection and maintenance to preserve crimp consistency

Usage recommendations

Use clean, correctly sized insulated ferrules from compatible reel formats and maintain the pneumatic system free of moisture and particulates. Periodically inspect crimp dies and cutting blades for wear and perform calibration checks on representative samples to ensure ongoing compliance with electrical and mechanical connection standards.
