Knipex 97 52 09 Crimping Pliers Two-Hand Operation 250mm Heavy Duty

The Knipex 97 52 09 is a 250 mm two-hand ferrule crimping plier designed for crimping insulated and uninsulated ferrules on conductor cross-sections up to 25 mm². A lever mechanism reduces required hand force by up to 30% compared to standard crimping pliers, and the factory-calibrated mandatory lock ensures the jaws do not open until the full preset crimp pressure is reached.

Features and benefits:

• Up to 30% less hand force required compared to standard crimping pliers, achieved through lever ratio
• Consistently high crimp quality delivered by precision-manufactured crimping profiles
• Mandatory lock prevents jaws from opening before the full preset crimp pressure is reached; lock can be released manually when needed
• Crimp pressure is precisely set and calibrated at the factory, with provision for field readjustment
• Two-hand operation simplifies crimping of large conductor cross-sections
• Balanced center of gravity, angled head, and ergonomically shaped handles for controlled and comfortable use
• Crimp insert is not exchangeable; tool is optimised for the three included nest sizes

Applications:

• Crimping insulated ferrules onto conductors from 10 to 25 mm² during control cabinet wiring
• Crimping uninsulated ferrules for industrial switchgear and panel assemblies
• High-volume electrical installation work where reduced operator fatigue is a priority
• Cable termination on large cross-section conductors in commercial and industrial environments
• Wiring of motor control centers and distribution boards requiring repeatable, reliable crimp connections
