Description
Cembre HNN4 Mechanical Crimping Tool
In short, the Cembre HNN4 is a compact hand crimper from Cembre’s CRIMPSTAR® range, designed for pre-insulated electrical connectors from 10 to 16mm².
It uses an indent crimp profile with a built-in ratchet, giving a simple, controlled way to crimp larger pre-insulated terminals without batteries or hydraulic equipment. As a result, the HNN4 suits electrical contractors, switchboard builders, maintenance teams and other professional users.
HNN4 10–16mm² Crimping Range
The HNN4 suits:
- Pre-insulated electrical connectors
- Conductor sizes from 10mm² to 16mm²
- Indent crimping
- Electrical installation and maintenance
- Workshop and field use
In all cases, always select a crimping tool to suit both the conductor size and the terminal manufacturer’s crimping requirements.
Ratchet Control and Crimp Jaws
A factory-set ratchet mechanism controls each crimping cycle, helping the operator complete the full crimp before the handles reopen — useful for repeated termination work. In addition, an emergency release lever lets the operator reopen the jaws early if needed.
Cembre uses treated steel for the HNN4’s crimping jaws, built for regular professional electrical work. Also, the jaws are fixed, so operators don’t need to select, change or store separate dies within the tool’s connector range.
Compact Cembre HNN4 Hand Crimper
The HNN4 weighs only 492g and measures 235 × 73 × 19mm, so it fits easily into tool bags and service vehicles. Furthermore, it operates entirely by hand — no batteries, chargers, pumps or hydraulic hoses required.

Applications for the Cembre HNN4
For example, the HNN4 suits many professional electrical applications, including:
- Switchboard and control panel manufacturing
- Electrical contracting
- Industrial electrical maintenance
- Equipment manufacturing
- Cable assembly
- Mining and resources
- Rail and infrastructure
- Utilities
- Field service and repairs
Because the HNN4 needs no batteries or hydraulic equipment, it also works well as a dedicated crimper for maintenance vehicles and field tool kits.
Choosing the Correct Cembre Crimping Tool
Cembre offers several CRIMPSTAR mechanical crimpers for different terminal types and conductor sizes. In particular, the HNN4 specifically suits pre-insulated electrical connectors from 10–16mm². However, conductor size alone doesn’t determine the correct crimping tool — non-insulated terminals, copper compression lugs, bootlace ferrules and other connector types may need a different Cembre crimper.
