Mersen/Ferraz Shawmut FR22AM69V25P Fuse – 22x58mm, 25A, 690V AC, aM Type with Striker

The FR22AM69V25P is a "partial-range" fuse, meaning it is engineered to handle massive short-circuit currents while allowing the motor's natural start-up surge to pass without tripping. The "P" suffix (and the item number Q213615) indicates this model includes a Striker (mechanical indicator). This small pin "pops" out upon fuse failure, which can be used to visually identify the blown fuse or to mechanically trigger a microswitch for remote signaling.
