BURNDY_YA25A7
BURNDY's compression connectors are designed for reliable and controllable electrical connections. The complete installation is fully inspectable. They are high conductivity copper and operate cooler than the wire on which they are installed. The connectors withstand a wide range of electrical and environmental conditions, including current surges, temperatures, corrosion and vibrations, for a wide variety of applications. These features mean a consistently high quality connection at a low installed cost. Copper compression connectors are manufactured from high-conductivity electrolytic copper. The connectors are normally tinplated, lead-plated, or plated with proprietary BURNDY® brite finish to provide durable long-lasting corrosion resistance. The connector design has been matched to the cable size to provide the necessary physical strength requirements for reliable electrical performance. Aluminum compression connectors are manufactured from high conductivity, high purity wrought aluminum. They are designed with sufficient mass and are electro-tin plated to minimize corrosion due to galvanic action between dissimilar metals. The connector barrels are pre-filled with PENETROX®, BURNDY's oxide inhibiting compound.

Manufactured from high conductivity, wrought aluminum with heavy duty wall thickness
Provides maximum conductivity, low resistance and ductility for an excellent combination of electrical and crimp forming properties
Provides durable long lasting corrosion resistance
Internally beveled barrel
Provides easy cable insertion
Provides a quality electrical dual connection
Connector is clearly marked with wire size, die index, color-code and the proper number and location of crimps
Provides easy identification and tooling recommendation for a proper compression which forms a homogeneous mass resulting in an excellent electrical connection
Factory prefilled with PENETROX® oxide inhibiting compound
Oxide inhibiting compound contains homogeneously suspended metallic particles to penetrate the wires oxides, establish electrical continuity and forms an airtight connection
Color-coded end caps inserted in barrel end
Prevents foreign materials from entering and contaminating the connector prior to usage plus identifies the proper color-coded die for a reliable connection
Type YA-A 2-hole pads inhibit connector rotation and increase area contact
These aluminum terminals have the same design features and benefits as the 1-hole YA-A with an added stud hole for a more secure termination to various types of equipment pads
For aluminum and copper conductors
3/0 AWG stranded conductor size
1-1/2 in L Strip, 1.75 in Hole Center to Center Distance, 0.63 in Hole Center to End, 0.74 in Hole Center to Barre
