Allen-Bradley 140G-H-TC3H Terminal Cover for Bulletin 140G Circuit Breakers

The Allen-Bradley 140G-H-TC3H (140G-H-TC3H) is a terminal cover engineered for use with Bulletin 140G H-frame molded case circuit breakers in industrial electrical distribution and motor control systems. Installed on three-pole circuit breaker assemblies, this protective terminal cover provides physical isolation and touch-safe shielding over power connection terminals, busbars, and cable lugs. By enclosing conductive terminations, it helps prevent accidental human contact with live electrical circuits, reduces the risk of phase-to-phase short circuits, and protects internal connections from debris and particulate accumulation. The component is intended for routine electrical maintenance, system upgrades, panel building, and direct field replacement across industrial control panels, switchboards, and motor control centers. It aligns with standard 140G frame mounting provisions to ensure secure mechanical retention and proper electrical clearance during regular operation. Integrating the protective cover maintains installation safety and integrity in demanding industrial environments where robust electrical infrastructure and dependable personnel protection are required.
