Electrical specialty fuses provide protection in a variety of applications. They are designed to protect circuits, equipment, and personnel from electrical overcurrent conditions. The MV155F1DBX80E is a self-resetting current limiting fuse with a very low clearance voltage rating. It is designed to protect critical applications with high current pulsing capabilities.

The MV155F1DBX80E fuse is most commonly used in applications that require high current pulses, such as motor drives, energy storage/conversion systems, renewable energy systems, and power conversion circuits. Other applications include industrial motor controllers, AC servo drives, solar inverters, LED lighting, servo amplifiers, AC motor variable frequency drives, HVAC systems, UPS systems, and electric power systems.

The MV155F1DBX80E is a fast-acting current limiting fuse with excellent pulse cycling capabilities. It features a low clearance voltage rating of 75V, which is ideal for providing overcurrent protection in sensitive electronic circuits. The fuse is capable of handling peak current levels up to 300A without resetting. This high current rating combined with the low clearance voltage rating ensures reliable protection of sensitive equipment and circuits.

The MV155F1DBX80E works by limiting the amount of current that can flow through it. It is designed to blow when a high current spike occurs, preventing the current from arc-faulting and damaging connected electronic components. When the fuse blows, it trips an internal thermal switch that keeps the circuit from resetting and allows it to cool down before allowing the circuit to be reset. This ensures that the circuit is protected from further overcurrent damage.

The MV155F1DBX80E is designed to meet the stringent requirements of IEC 60269-2 for high interrupting capacity and low voltage let-through tests. The fuse has a 100%rated current capability and meets UL, CSA, and TUV standards. It is also approved by several major OEMs, including Siemens, ABB, and GE. The fuse is UL Classified as a high-speed current limiting device.

The MV155F1DBX80E is ideal for protecting sensitive circuits from overcurrent damage. It features a low clearance voltage rating and excellent pulse cycling capabilities, as well as meeting all relevant standards for high interrupting capacity and voltage let-through tests. The fuse is suitable for a wide range of industrial and commercial applications, providing reliable overcurrent protection for critical circuits.
