Screw Type Fuse is composed of cap, fuse tube, ceramic body, chemically treated quartz sand and indicator. It has many advantages and uses and is suitable for many environments. Zhejiang Zhenghao Fuse has launched Screw Type Fuse after listening to customer opinions and market demands.
Type | Spiral | Plug-in | Enclosed |
Breaking Capacity | High judgement ability | Low(applicable to end circuits) | Extremely High(industrial grade protection) |
Maintain convenience | Easy to operate | Plug and unplug operation required | Replace the melt core as a whole |
Applicable environment | Vibration and dusty environments | Dry and stable environment | High risk flammable environment |
1. Under normal current, the temperature and heat dissipation of Screw Type Fuse are very stable, and the conduction state is maintained.
2. When the current exceeds the rated value (such as short circuit or severe overload), the Screw Type Fuse will quickly melt in seconds, and the chemically treated quartz sand will absorb the arc energy as the arc extinguishing medium to achieve safe control.
3. The ceramic fuse has a built-in indicator. The indicator is triggered after the fuse is blown, which can be seen through the porcelain cap.
1. High breaking capacity, the quartz sand arc extinguishing design can withstand a current short circuit of up to 200A.
2. At the beginning of the design, considering the space utilization, the small size and high utilization rate, such as limited distribution cabinets and control boxes, can be applied.
The fully enclosed structure is dustproof and vibration-resistant, and is also very suitable for harsh environments such as machine tools and electric locomotives.
1. Rated voltage: AC 500V and below.
2. Rated current: Screw Type Fuse has various specifications, covering 2A-200A (such as Zhenghao's RL1 series).
3. Breaking capacity: up to 20KA (depending on the corresponding model).
Through China CCC and IEC International Electrotechnical Commission IEC and GB/13539 and other standards, the breaking performance and insulation level are ensured.
