18.Z2.F04-1003 by KEB

The KEB 18.Z2.F04-1003 three-phase motor choke from the Z2 Three Phase Motor Chokes series by KEB delivers robust suppression of line disturbances and ensures stable performance in demanding industrial drives. Available in both IP20 and IP00 protection class versions, this choke provides flexibility for a range of installation environments. It withstands an overload capacity of 150% for 60 s, making it ideal for applications with frequent load surges. The primary function of the 18.Z2.F04-1003 is to filter harmonics and limit voltage drops in three-phase motor circuits, thereby enhancing motor drive reliability and extending component life.

Engineered to meet stringent technical standards, the 18.Z2.F04-1003 complies with EN 61558-2-20, VDE 0160 technical principles and achieves a voltage drop (Uk) of 4% under rated conditions. Its convection cooling design ensures efficient thermal management without auxiliary fans, while the max. leakage current of 0 mA eliminates unwanted ground current. Rated to climate category 3K3 (EN 60721-3-3) and vibration/shock tolerance 3M4 (EN 60721-3-3), this choke stands out for its resilience in harsh environments. Dual certification by UR and cUR underscores its global compliance and safety credentials.

Additional features include a pollution level 2 (IEC 664-1) classification and versatile installation positions—either standing or lying horizontally—to accommodate space constraints in control cabinets. The operating temperature range of -10 ... 45 °C and storage capability down to -25 °C (up to 70 °C) guarantee durability under extreme conditions. By maintaining power quality and reducing motor stress, the 18.Z2.F04-1003 improves efficiency and system uptime. Its compatibility with standard three-phase motor drive systems and adherence to industrial performance standards make it a reliable choice for automation and drive applications across manufacturing, processing, and material handling industries.
