Electrical failures – short-circuit and wire-disconnection – are mostly caused by defective wire terminations because of operator skills.
Push-in CAGE CLAMP® is the universal connection technology for all conductor types that provides the simplicity of push-in terminations ensuring long-term contact quality, independent of operator skills and designed for harshest environments – steady vibrations and high temperature variations.
Vibration and shock-proof and maintenance-free
The vibration-proof properties of Push-in CAGE CLAMP connections have been tested and successfully validated in a vibration test to IEC/EN 60068-2-6. In this test, a frequency band up to 2000 Hz, at different accelerations up to 20g and different amplitudes up to 20mm, is passed continuously in three axes.
Additionally, international authorities have placed extremely demanding requirements on electrical installations in rolling stock (IEC/EN 61373); multiple marine agencies (e.g. GL, LR and DNV) have declared that Push-in CAGE CLAMP meets their lofty approval standards.
Maintenance-free operation results from excellent long-term consistency of the electrical and mechanical properties of the clamping connection – or more precisely, the clamping unit.
Push-in CAGE CLAMP spring pressure terminals are suitable for all conductor types: solid, stranded and fine-stranded conductors, as well as fine-stranded conductors with ferrules or pin terminals, and tip-bonded conductors. Moreover, all conductors can be connected without any preparation and ferrules and pin terminals can be used, but are not mandatory.
High contact quality
In addition to correctly selecting the materials and surface coating, the contact pressure determines the quality of the clamping connection. The conductor is pressed against the current bar in a predefined contact area without damage.
The contact zone is deliberately designed to be small and curved, not flat, in order to exert high contact pressure. The clamping force adjusts automatically to the conductor size. The clamp dynamically compensates for conductor deformation due to flow effects.
A superior design eliminates the risk of a loose connection; contact breaks are excluded. The conductor is embedded in a soft tin layer. The transition point is resistant to corrosive infiltration. The long-term consistency of the contact resistance is ensured – even in aggressive atmospheres.
Connection technology made simple
Pull the lever up, insert a conductor and push the lever back down. The ingeniously simple connection technology that has made WAGO’s 221 Series Junction Box Connector a popular all-purpose solution is now DIN-rail ready as the newest variant to WAGO’s trusted TOPJOB®S Rail-Mount Terminal Block family.
This means that even in the control cabinet, conductors can now be easily connected by hand and removed without tools. The user benefits from simple and intuitive use, especially for in-the-field wiring. The terminal point is clearly marked by the open lever, which reduces the risk of forgetting terminal points when wiring or connecting conductors incorrectly.
In addition, both hands remain free for wiring because the clamping unit does not need to be kept open with an operating tool. This convenience facilitates connecting difficult-to-bend conductors with large cross sections.
