According to the present invention, provided is a fuse assembly for an inverter protection device, which is capable of delaying a fusing time due to overcurrents in an energy storage system, by forming a fuse wire inside the fuse assembly in a spiral shape. The fuse assembly for an inverter protection device includes: first and second electrodes which transmit an applied current; a ceramic tube which has one side coupled to the first electrode and the other side coupled to the second electrode, and includes a hollow part through which a central portion in the longitudinal direction is penetrated; and a fuse wire which is positioned in the hollow part of the ceramic tube to transmit the current between the first electrode and the second electrode, and functions as a fuse element that is fused by an overcurrent flowing through the first electrode and the second electrode. The fuse wire is formed in a spiral shape. 본 발명에 따른 인버터 보호 소자용 퓨즈 조립체는 인가되는 전류를 전달하는 제1 전극 및 제2 전극; 일측이 상기 제1 전극과 결합되고 타측이 상기 제2 전극과 결합되며, 길이방향의 중심 부분이 관통된 중공부를 포함하는 세라믹 튜브; 및 상기 세라믹 튜브의 상기 중공부 내에 위치하여 상기 제1 전극과 상기 제2 전극 사이에서 상기 전류를 전달하고, 상기 제1 전극과 상기 제2 전극에 흐르는 과전류에 의해 용단되는 가용체로 기능하는 퓨즈선을 포함하고, 상기 퓨즈선은 나선 형태인 것을 특징으로 한다.
