MERSEN FUSE 250V SU 6,3 A 5.20 MI5SU25V6,3

Why Choose the Mersen P087505 Semiconductor Fuse?

The Mersen P087505, also identified by the reference MI5SU25V6,3, is a compact 5 x 20 mm very fast-acting cartridge fuse designed to provide precise overcurrent and short-circuit protection for sensitive semiconductor devices and electronic circuits. Manufactured by Mersen, this specialist fuse combines a small physical footprint with the rapid operating performance required by modern industrial electronics.

Unlike general-purpose fuses, the P087505 has a very fast-acting SU semiconductor protection characteristic. This allows the fuse to interrupt potentially damaging fault currents quickly, helping protect delicate components such as power semiconductors, rectifiers, control modules and electronic power supplies.

With a rated current of 6.3 A and a rated voltage of 250 V, the Mersen P087505 is suitable for use in compatible 5 x 20 mm fuse holders within industrial automation equipment, electronic assemblies and power conversion systems.

Fast Protection for Sensitive Electronic Components

Semiconductor devices can be damaged by fault currents in a fraction of a second. The Mersen P087505 is engineered to operate much faster than conventional time-delay or general-purpose fuses, limiting the electrical energy passed through the protected circuit during a fault.

Its very fast operating characteristic makes it particularly suitable for power electronic circuits where rapid isolation is essential. The compact cartridge construction also allows the fuse to be incorporated into control boards, power supplies and industrial electronic equipment where installation space is limited.
