A fuse support(2) and two fuse holders(21) are placed at tops of the input terminal(1) and the fuse support(2). Fuses(22) are mounted at the fuse holders(21). A primary winding(41) consists of one. An iron core(43) is placed at upper, lower and perpendicular directions of the primary winding(41). Terminals are fixed at left and right sides of a main body, and a terminal is fixed at a lower side thereof. The main body is made of fire retardancy plastics, and the fuse support(2) is capable of being detaching by a bolt(23) according to the attachment of the fuse(22).
