    ABB 3HAC7344-1 is a high-performance power line filtering unit designed specifically for industrial power systems. Its core function is to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) in industrial power lines, providing a clean and stable power environment for ABB automation equipment such as robots, DCS controllers, and servo drives. As a key "interference barrier" in the industrial power supply chain, it can effectively filter out common mode interference and differential mode interference in the power grid, while preventing the interference generated by the equipment itself from feedback to the power grid, avoiding damage to sensitive electronic components caused by interference, and ensuring the long-term stable operation of automation systems.

Multiple safety protection design: Built in self recovering fuse for overcurrent protection, avoiding overload that may cause the filtering unit to burn out; Varistors and surge protection circuits can withstand power grid surges (such as lightning induced surges), withstand 5kA (8/20 μ s) surge currents, and protect backend equipment power interfaces from overvoltage impacts; 2500V AC withstand voltage design between the circuit and the casing to prevent safety accidents caused by leakage.

Convenient installation and compatibility expansion: Supports two installation methods: DIN rail and screw fixation, suitable for different control cabinet layouts; The input/output terminals are connected using screw terminals, with a spacious terminal spacing (≥ 5mm) for easy wiring and inspection; It can be used in series with ABB power modules (such as 3HAC031663-001) and UPS equipment to build a multi-level power supply protection system.

Low loss and silent operation: The power consumption of the filtering unit itself is ≤ 3W (at rated current) to avoid energy waste; The common mode inductor adopts iron powder core magnetic core, which has no electromagnetic noise during operation (operating noise ≤ 30dB), and is suitable for noise sensitive industrial environments (such as electronic component assembly workshops).
