A fuse suitable for arc quenching is disclosed. The fuse incorporates a high-resistive material or element placed in parallel relationship with the fusible element to mitigate, minimize and/or prevent arcing during an overcurrent condition. By incorporating a high-resistive material or element in parallel with a fusible element an alternate or second path for current flow during an overcurrent condition is provided. As such, during normal operating conditions, current travels through the fusible element. However, during an overcurrent condition, the resistance through the fusible element increases. Once the resistance through the fusible element is greater than the resistance through the high-resistive material or element, the current will bypass the fusible element and travel through the high-resistive material or element. In this manner, arcing through the fusible element during the overcurrent condition can be prevented or minimized.
