Overview

The ABB NC303 Clamp-Type Connector (SKU: NC303) is a precision-engineered solution for securing 1-inch rigid or EMT conduit in industrial, commercial, and residential electrical installations. Constructed from durable die-cast zinc, this connector delivers superior corrosion resistance and long-term mechanical strength, ensuring reliable performance in demanding environments. The clamp-type design features an adjustable clamping range from 0.34 to 0.94 inches, accommodating minor conduit size variations while maintaining a secure grip. With a compact width of 1.95 inches, the NC303 fits standard junction boxes and enclosures without excessive bulk. Installation is simplified by the tool-free clamp mechanism, reducing labor time compared to threaded or set-screw alternatives. This connector meets industry standards for electrical safety and is ideal for applications requiring vibration resistance, such as machinery enclosures, control panels, and HVAC systems. The zinc construction provides excellent conductivity for grounding purposes, while the smooth internal bore minimizes cable abrasion during installation. Compatible with EMT, IMC, and rigid steel conduit, the NC303 is a versatile choice for electrical contractors, maintenance teams, and facility managers seeking a cost-effective, high-reliability conduit connection solution.
