Product Overview

The ABB 3AFE64803689, identified by the type designation CBHX165C5R414, is a high-performance charging resistor specifically engineered for ABB industrial drive systems. As a critical component of the DC link pre-charge circuit, the ABB 3AFE64803689 serves the essential function of limiting inrush current when the drive is first powered on, protecting the rectifier bridge and DC bus capacitors from potentially damaging surge currents . The ABB 3AFE64803689 is designed for intermittent, pulse-duty operation during the start-up sequence, typically engaging for a few seconds to allow the DC link capacitors to charge smoothly before the main contactor closes .

The ABB 3AFE64803689 CBHX165C5R414 features a robust aluminum alloy or ceramic housing designed for panel mounting within the drive cabinet . Its 5 Ω resistance value is precisely specified to limit the initial charging current to a safe level, preventing damage to the drive’s power electronics . The ABB 3AFE64803689 is compatible with a range of ABB drives, including the ACS800, ACS880 (small-to-medium power units), and DCS800 DC drives, making it a versatile replacement part for maintaining critical drive systems .
