Simple Assembly In-Line Power Connectors for up to 160A EF1 Series Features 1. Simplified assembly The crimp contact itself becomes the connector in a few simple steps by crimping the contact directly to the power cable and then inserting it into the housing. 2.Quick, snap in lock Its snap-in structure reduces assembly costs due to its simplicity and ability to reduce wiring steps. This connector does not need screws like traditional terminal block connectors. 2 3.160A rated current capacity when using 38mm cable 2 Supports 5.5, 8, 14, and 22mm cables by utilizing a 2 sleeve to convert the conductor diameter to 38mm . 4. Multiple mounting options Attached to a DIN rail or secured to a panel, this connector is versatile enough to be used in a wide range of mounting applications. 5. Simplified crimp terminations No special tools are required. 6. Equipped with guide keys Guide keys are used to prevent incorrect wiring. 7. Pending TV, UL certifications Testing is underway to get this series qualified for various safety standards. 8. RoHS compliant All materials and substances used to produce this product comply with the RoHS compliant standards.
