Why Choose the Mersen X097540 BS17US25V16P Semiconductor Fuse?
The Mersen X097540, catalogue number BS17US25V16P, is a Protistor® BS88-4 high-speed semiconductor fuse-link specifically engineered to protect sensitive power semiconductor devices against damaging short-circuit currents. Featuring an ultra-fast aR operating characteristic, it delivers rapid fault clearance for IGBTs, thyristors, diodes and rectifier modules used in industrial power electronic equipment.
Rated at 16 A, the fuse provides 250 V AC IEC, 250 V AC UL and 300 V DC UL ratings. The compact 17 × 27 mm BS88-4 format incorporates an integrated striker indicator, allowing rapid identification of a blown fuse and optional remote signalling when used with a compatible microswitch.
Manufactured using Mersen's proven Protistor® technology, the BS17US25V16P offers excellent current limitation, very low let-through energy and an exceptionally high 250 kA breaking capacity, helping to minimise damage to expensive semiconductor components while improving equipment reliability.
