INTRODUCTION This specification covers the requirements for application of the Snap-Lug Quick Disconnect Power Connector. These connectors are single-pole quick-connect/disconnect bus bar connectors used in bus bar and power distribution applications. The connectors are designed to be used where standard terminal lugs with wire sizes of 4, 1/0, 2/0, and 3/0 AWG. The high power connectors are available in silver finished male post contacts and tin finished female socket contacts as well as four color coding options to confirm polarity. The connector design will reduce the labor during assembly and enable faster system maintenance. The connector design features a positive latching mechanism with an audible click sound and tactile feel to confirm a full mate. The socket contact is a right-angle configuration consisting of a housing and latch subassembly and a conductive socket contact body with a LOUVERTAC contact band with silver finish. The post contact features a keying ring and a socket latching feature on top of the post contact. The keying ring and the socket housings are available in red and black. Contact TE for other colors for polarity requirements. The socket contact will accept MS22759 or equivalent standard wire sizes 4, 1/0, 2/0, and 3/0 AWG or nonmilitary wire with equivalent CMA, with 4 indent crimp termination tooling. See Figure 2. If nonmilitary wire is used in the application, the performance may vary from the design intent per Product Specification 108- 32083. A heat shrink boot or a heat shrink tubing shall be used to secure the housing and wire together for insulation and strain relief. Heat shrink tubing and boots are determined by the customers requirements. Examples of common heat shrink tubing and boots are as follows. More details are available at TE.com. Higher temperature o o o o options: DR-25 (150 C), RT555 (200 C), RT-780 (175 C), or RT-790 (200 C). Lower temperature options: o ATUM-24/8, ATUM-24-6, or TAT-125. Dual Wall ATUM 24/8, ATUM 24/6 or TAT-125, all 110 C rated. Boot options: 202D221-3 with 202D221-25, or 202G621-55.

Specifications Product Specification 108-32083 provides product performance and test results. 3. REQUIREMENTS 3.1. Safety 1. Do not stack product shipping containers so high that the containers buckle or deform. 2. Safety interlocks and/or insulating devices must be designed into the system to avoid inadvertent electrical shock. 3. Applying current loads higher than the recommended values in the 108-32083 can cause the product to not perform as designed. DANGER To avoid personal injury, the electrical system must be de-energized before installing or removing any connector and before mounting or removing connectors from the bus bar or backplane. 3.2. Storage A. Ultraviolet Light Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the product material. B. Shelf Life The product should remain in the shipping containers until ready for use to prevent deformation to components. The product should be used on a first in, first out basis to avoid storage contamination that could adversely affect performance. C. Chemical Exposure Do not store product near any chemical listed below as they may cause stress corrosion cracking in the material.
