Why Choose the Mersen W230088 A15QS40-1 Semiconductor Fuse?
The Mersen W230088 (A15QS40-1) is a high speed semiconductor fuse from the proven Amp-Trap® A15QS Series, specifically engineered to protect sensitive power semiconductor devices operating on circuits up to 150 VAC/DC. Its compact North American Form 101 design makes it ideal where installation space is limited while still providing rapid fault interruption and low let-through energy.
Designed for the protection of diodes, SCRs, IGBTs, rectifiers, UPS systems and AC/DC drives, the W230088 rapidly clears short-circuit faults before damaging levels of thermal and electrical energy can reach critical semiconductor components. Its fast-acting characteristic helps minimise equipment damage, reduce downtime and improve system reliability.
With a rated current of 40 A, voltage ratings of 150 VAC/DC, interrupting ratings of up to 100 kA DC and 50 kA AC, and a cylindrical ceramic body with ferrule terminals, the Mersen W230088 is well suited for industrial control systems, power electronics and OEM equipment requiring dependable semiconductor protection.
