A protection fuse is a safety device that interrupts electrical current flow in capacitor bank arrays during overcurrent or short-circuit conditions to prevent equipment damage and ensure operational safety.

The primary purpose is to provide reliable overcurrent and short-circuit protection by interrupting fault currents before they can damage capacitors, cause thermal runaway, or create fire hazards.
Selection requires matching rated voltage and current to system specifications, ensuring breaking capacity exceeds maximum prospective short-circuit current, and choosing appropriate time-current characteristics (typically gG/gL type for full range protection).
Undersized fuses may cause nuisance tripping during normal operation or fail to interrupt high fault currents, potentially leading to capacitor damage, equipment failure, and safety hazards.
