The special non-flammable silicone coating utilized in the construction of the AC-CS helps prevent flame or explosion when an AC mains voltage of 115V_AC or 230V_AC is applied. To compare, fusible resistors offered by competitors produce heavy and visible sparks under similar overload conditions. In addition to being non-flammable, the specially developed lacquer coating meets the excellent thermal and electrical insulating properties of standard silicone cement coatings.
