The Allen-Bradley 140G-K6X4 circuit breaker is a 140G molded case circuit breaker with a K frame type and a current rating of 400 Amps. This is a product from Eaton Cutler-Hammer that is manufactured as part of the 140G series of molded case circuit breakers. It features an interrupting rating of 65 kA, with 4 poles and a breaker frame protection type. It also comes with frame-only current range and an insulation voltage rating of 1000 Volts. The 140G-K6X4 circuit breaker features an impulse withstand voltage rating of 8 kV and an approximate weight of 9.15 pounds. It is available in a wide range of fault interruption ratings ranging from 25 to 200 kA to address the needs of various applications. This device comes with customer-friendly accessories which enable easy and quick setup of nearly any type of project.

This Allen-Bradley 140G-K6X4 molded case circuit breaker boasts worldwide support from Allen-Bradley for UL or IEC project types. With basic or advanced OCRs like AC electronic and AC or DC thermal-magnetic protection types, this trip unit is suitable for a wide range of installation requirements. Additionally, it supports the reverse connection of the power supply and a UI insulation voltage rating of 800 Volts (RMS). Generally, the molded case circuit breakers like the 140G-K6X4 circuit breaker are engineered and intended to provide overcurrent protection for equipment as well as conductors by opening spontaneously before the current level reaches a level that may result in a hazardous temperature in the conductor insulation for a prolonged period. Furthermore, this 140G device serves as the control panel’s primary means for disconnection, as well as a means of short-circuit current protection and reduced overcurrent protection.
