Allen-Bradley 140MT-C3E-C16 Motor Protection Circuit Breaker 10-16A C-Frame

Product Description

The Allen-Bradley 140MT-C3E-C16 is a compact and reliable motor protection circuit breaker (MPCB) from the Bulletin 140MT series, designed to provide short-circuit and thermal overload protection for electric motors. Featuring a Frame C design with high interrupting capacity, it offers an adjustable thermal trip setting range of 10 to 16 A and a fixed magnetic trip threshold to prevent damage during high fault conditions. Built with a rotary door/lockable operator and designed for standard 35 mm DIN rail or panel mounting, it is ideal for motor control circuits, group motor installations, and self-protected combination motor controllers (Type E/F).
