The present invention provides a compact explosion-proof protector. The compact explosion-proof protector comprises a melt, electrodes, an encapsulation layer and an arc extinguishing material; two electrodes are provided; the melt is arranged between the two electrodes; the arc extinguishing material is attached onto the melt; the encapsulation layer forms a cavity; the melt is located in the cavity; and the electrodes pass through the encapsulation layer. The arc extinguishing material is made of the following components in parts by weight: 10 to 12 parts of polyamide resin or polyimide resin or silica gel resin; 4 to 8 parts of anhydrous magnesium hydroxide; 3 to 7 parts of fumed silica; and 0.1 to 0.5 part of sodium chloride. The compact explosion-proof protector of the invention has the advantages of decreased size and improved explosion-proof performance. 本发明提供种紧凑型防爆保护器，包括熔体、电极、包封层、灭弧材料。电极设置两个，熔体设置于两个电极之间，灭弧材料附着于熔体上，包封层形成空腔，熔体位于空腔内且电极穿过包封层；所述灭弧材料按重量比包括下述组分：聚酰胺树脂或聚酰亚胺树脂或者硅胶树脂10～12份，无水氢氧化镁4～8份，气相二氧化硅3～7份，
