MERSEN FUSE 690V FA 0,25 A 6.32 MI6FA69V0,25

Why Choose the Mersen V093283 MI6FA69V0.25 Miniature Fuse?

The Mersen V093283, catalogue number MI6FA69V0.25, is a compact high-speed semiconductor miniature fuse developed to protect sensitive electronic components against damaging overcurrents and short circuits. Its very fast-acting FA characteristic provides rapid fault interruption, helping limit the thermal and electrical energy reaching vulnerable semiconductor devices.

With a rated current of 0.25 A and a rated voltage of 690 V AC, the V093283 is suitable for low-current circuits operating at elevated voltages. Its standard 6.3 x 32 mm ceramic cartridge construction allows straightforward installation in compatible fuse clips and holders.

The fuse offers a minimum interrupting rating of 30 kA, supporting reliable clearance of substantial prospective fault currents. Manufactured by Mersen, it provides dependable protection for power conversion equipment, industrial automation systems, instrumentation and other sensitive electronic applications.
