Overview

The TE Connectivity 556879-3 Rectangular Power Connector is a 3-position wire-to-board solution engineered for high-reliability power transmission in industrial, automotive, and telecommunications applications. Designed with an 11.18 mm [0.44 in] centerline spacing, this connector ensures precise pin alignment and secure mating in compact electrical assemblies, reducing the risk of misalignment or accidental disconnection. The housing is constructed from UL 94V-0 rated materials, meeting strict flammability standards for safety-critical environments where fire resistance is essential. Its robust design supports efficient power distribution while maintaining electrical integrity under demanding conditions, including high vibration, temperature fluctuations, and exposure to moisture or contaminants. The wire-to-board configuration simplifies installation by allowing direct termination to standard wire gauges, eliminating the need for additional adapters or complex wiring harnesses. This design enhances system reliability by minimizing connection points and reducing potential failure modes in high-stress applications. Compatible with common industrial wiring practices, the 556879-3 delivers consistent performance in harsh operating environments, such as factory automation, motor control systems, and power distribution units. Its durable construction and TE Connectivity’s proven reliability make it a cost-effective choice for engineers seeking a dependable power connector solution. The connector’s compact footprint and high current-carrying capacity further contribute to its versatility in space-constrained designs.

Use the NSI HTGE-250 Two-Way Basket Ground Clamp to ground electrical connections in distribution/pole transformers. This clamp is cast from high conductivity copper alloy and comes with cast bronze eyebolts, both of which are high strength and guarantee durable performance when grounding transformers in harsh environments. Strong stainless-steel nuts and lockwashers are standard on all two-way basket ground clamps. Additionally, the flat surface acts as a seal to the tank. HTGE series ground clamps provide a hex or square shoulder for wrench tightening and come tin plated by adding the suffix ‘TN’ for additional corrosion resistance. Use the HTGE-250 when running ground wire in the range of 6 SOL to 250 MCM. Stock products you can rely on—stock NSI.
