What is Y capacitor?
A "Y" capacitor is used in line-bypass applications. Typically between the hot line and ground or neutral and ground in North American applications and between L-1 or L-2 and ground in European and other power-line applications. The definition for "Y" capacitor application is: "where damage to the capacitor may involve the danger of electrical shock." The "Y" classification is divided into four sub-classifications, Y1, Y2, Y3, Y4 as defined by EN132400.
