Product Description:

The 13.Z1.B04-1000 is a sine-wave electromagnetic compatibility filter produced by KEB within the Z1 Sine Wave EMC Filters series. It is designed for installation between a variable-frequency drive and a three-phase motor. The component smooths the inverter’s pulse-width-modulated output so that cable-borne emissions are lowered and motor insulation stress is reduced in industrial automation systems.

Electrically, the filter is specified for a line voltage of 400 VAC and can continuously carry 12.6 A of current while serving equipment on a three-phase network. It withstands transients up to 550 V without breakdown, and its internal construction limits power dissipation to 48 W under nominal loading. With maximum leakage current rated at 0 mA, the unit simplifies ground-fault monitoring in sensitive installations. Pollution degree 2 classification confirms suitability for control cabinets with only non-conductive contamination. A copper fill mass of 0.7 kg helps achieve low differential-mode impedance across the required frequency band. This thermal margin also prevents premature insulation aging during continuous service.

Mechanical integration is straightforward because the housing relies on convection cooling rather than forced air, avoiding extra fans or ducts. The assembly stands 145 mm tall, projects 148 mm from the mounting base, and spans 78 mm in width, giving a compact rectangular footprint. Total mass is only 2.6 kg, so panel builders can secure the filter without reinforcement. To keep drive output within tolerance, the series impedance introduces a controlled voltage reduction of 4%. Field wiring is completed with terminals sized for 4 mm² conductors, and the inductor’s laminated core voltage drop characteristic remains stable because of the low operating temperature rise created by the copper fill noted earlier.
