The dual-element construction uses separate overload and short-circuit elements in series, providing time-delay performance that tolerates motor inrush currents and transformer magnetizing inrush while still providing fast response to sustained overloads and short circuits. The RK5 rejection feature — visible as the notched lower blade terminal — physically prevents installation in older, non-rejection-style Class H fuse holders, enforcing the use of higher-rated RK5 rejection fuse holders. Typical applications include branch circuit protection for motors, transformers, service entrance equipment, and feeder circuits operating at 250V AC or below. This fuse ships new in original Mersen packaging with part number TR150R confirmed on both the fuse body label and box.\u003c\/p\u003e\n\u003ch3
