Présentation du produit
The Allen Bradley 140G-K3F4-D40 Molded Case Circuit Breaker is a high-performance molded case circuit breaker (MCCB) designed to provide reliable protection for industrial power distribution systems. As part sur the 140G series, this model is built to handle demanding electrical loads while ensuring safety against overloads and short-circuit conditions.
With a rated current sur 400 A and a breaking capacity sur 35 kA at 480 V, this breaker is suitable for medium to high-power applications. The K frame design surfers a compact footprint while maintaining high interrupting capacity. It features a thermal-magnetic (T/M) trip unité with adjustable thermal and magnetic settings, allowing flexible protection tuning based on system requirements.
This 4-pole configuration makes it ideal for applications requiring neutral line protection or complete circuit isolation. Designed as an 80% rated MCCB, it ensures stable continuous operation within defined limits. The unité is panel mountable and does not support bus bar mounting, surfering flexibility in installation.
