FMBC LL data sheet - .PDF file.

SCHURTER has expanded its FMBC NEO three-phase filter range with the FMBC LL, a low-leakage current series for applications where no high leakage currents are allowed. The FMBC LL series of filters is designed for rated currents between 7A and 180A and is said to be ideal for leakage-current-critical applications such as drive technology and high-power systems, such as machines used in an industrial environment.

Today’s electrical industrial installations are increasingly being fitted with residual current devices (RCD) to ensure efficient personal protection. This is also a requirement in certain countries for three-phase systems — for example, plug-in systems up to 32A.

The RCD limits the current to earth to a maximum of 30mA. This poses a particular problem in drive technology since the frequency inverters that control the engine generate considerable leakage current. Long motor cables further aggravate the problem since they increase the capacity to earth and hence the currents to earth too. The FMBC LL filters help reduce the leakage currents and permits compliance with common EMC standards as an efficient input filter.
