Snap-Lug Quick Disconnect Power Connectors – The Next Generation of Terminal Lugs

Snap-Lug Quick-Disconnect Power Connectors from TE Connectivity (TE) are ruggedized power disconnectsdesigned to provide a quick method for interconnecting heavy gauge power cables to bus bars, relays, power panels, and similar applications in aerospace, defense, and marine, and other harsh environment applications. These connectors have been engineered to replace traditional terminal lugs with safe, reliable, quick-disconnect, keyed locking connectors, enabling applied cost-savings.

Easy to Use

• Snap on/push to release; no tools required
• Color-coded and keyed connector prevents reverse polarity
• Enables connections in confined spaces

Safe and Secure

• Provides a touch-proof connection that helps prevent accidental shock under power
• Locking feature prevents unintentional disconnect in challenging environments
• Sealed interface prevents contamination
