Ferruled conductor cross-sections specified for WAGO
products are based this crimping method.
• Built-in ratchet mechanism ensures gas-tight crimp
connection.
• Ergonomically designed handles.
What “gas-tight” connection?
In gas-tight connection, the conductor and the ferrule
are compressed, eliminating all spaces.
Inadequate crimping can allow the conductor be
pulled out the connection Hollow spaces also remain,
permitting oxidation formation and leading increase
in contact resistance.wago.com

Item No.
Elevated resistance detrimental for both signal trans-
mission (signal flow damped) and power transmission,
resulting power loss and contact heating (risk fire). These tools open
automatically after the crimping operation complete.
Oxidation between crimped single conductors prevent-
ed, virtually eliminating the possibility any increase in
the crimped connection’s resistance. However,
these instances can considered closed off due to
the twisted conductor.
Application notes:
• Improved crimping for higher conductor retention
• Crimping can performed from either side (for left- or
right-handed users). Pack. Squeeze handles until ratchet mechanism released. Unit Item No. some exceptional
cases, minute, isolated spaces may present.

• Crimping tools open automatically after crimping opera-
tion complete. Under normal
atmospheric conditions, neither liquid nor gaseous
medium can penetrate the crimped connection.
Crimping tools with built-in ratchets are recommended,
such the WAGO Variocrimp tools.
