Product Description:

The 17.Z1.C04-1001 is a sine-wave electromagnetic compatibility filter produced by KEB and supplied within the Z1 Sine Wave EMC Filters series. In automated drive panels, the unit is installed between the inverter and the motor to smooth pulse-width-modulated output, reduce dv/dt stress on motor windings, and limit conducted emissions that could interfere with nearby control electronics. This helps protect insulation, extend cable life, and improve the electrical behavior of the motor connection. It is intended for cabinet-mounted drive systems that use longer motor leads or operate close to sensitive signal wiring.

In operation, the filter handles a rated load of 18.5 kW at a bus voltage of 400 V. Its continuous current capability is 44.1 A, so it can serve medium-frame induction or permanent-magnet motors without saturation. Copper bars sized for a 16 mm² line connection provide low impedance, while a dedicated M8 PE stud bonds the housing to cabinet ground. Despite its iron-core construction, the device dissipates only 255 W under full load, and an efficiency of > 99% helps keep thermal rise low. Total harmonic distortion on the input side remains at or below 15%, which reduces neutral conductor heating and helps upstream breakers operate within nominal limits.

The mechanical format follows climatic category 3K3, meaning the assembly tolerates indoor environments with moderate humidity and dust. Overall width is 291 mm, height is 140 mm, and the housing depth leaves room for natural-convection airflow around the core. A mass of 27.0 kg provides substantial thermal inertia for continuous-duty operation without external fans. The enclosure carries a protection rating of IP20, so live parts are finger-safe while ventilation openings remain available for passive heat dissipation.
