Why Choose the Mersen H203764 MIBOX5ST Miniature Fuse Assortment?
The Mersen H203764 MIBOX5ST is a practical assortment of 5 × 20 mm time-delay miniature fuses designed for electrical maintenance, equipment servicing and industrial circuit protection. Containing a selection of current ratings from the established Mersen 5ST IEC miniature fuse series, it provides engineers and technicians with convenient access to commonly required slow-blow fuse ratings.
The time-delay operating characteristic allows the fuses to withstand brief, high start-up currents without unnecessary operation. This makes the assortment particularly useful for protecting equipment containing motors, transformers, power supplies and other components that naturally draw an inrush current when energised.
Designed for circuits rated up to 250 V AC, the H203764 assortment contains 5 × 20 mm glass cartridge fuses covering current ratings from approximately 0.1 A to 6.3 A. The organised storage box is suitable for maintenance workshops, panel builders, laboratories, OEM production facilities and industrial service departments.

Convenient Protection for Circuits with Inrush Current
Time-delay miniature fuses are designed to withstand temporary current surges associated with normal equipment start-up while still disconnecting the circuit during a sustained overload or short circuit. This helps prevent nuisance fuse operation in equipment containing motors, transformers and capacitive loads.
By providing several commonly required ratings in one organised box, the Mersen H203764 helps maintenance engineers select an appropriate replacement fuse quickly. This can reduce equipment downtime and simplify stock management in workshops, service vehicles and production environments.
