MERSEN FUSE 250V SU 2 A 5.20 MI5SU25V2

Why Choose the Mersen J087500 Time-Delay Miniature Fuse?

The Mersen J087500 is a robust 5 × 20 mm high-breaking-capacity time-delay fuse designed to protect industrial, commercial and electronic equipment against sustained overloads and short circuits. Part of the established Mersen 5SU miniature fuse series, it combines reliable fault interruption with tolerance of temporary start-up currents.

Its time-delay operating characteristic allows brief inrush currents from transformers, motors, power supplies and capacitive loads to pass without unnecessary fuse operation. This helps reduce nuisance fuse replacement while maintaining dependable protection when an excessive current condition persists.

With a rated current of 2 A, a rated voltage of 250 V AC and compact 5 × 20 mm dimensions, the Mersen J087500 provides an effective circuit protection solution for control panels, instrumentation, automation equipment and OEM electrical assemblies.

Reliable Protection for Circuits with Inrush Current

Time-delay miniature fuses are designed to withstand brief current surges that occur during normal equipment energisation. Unlike quick-acting fuses, they do not immediately operate when a short-duration inrush current passes through the circuit, helping prevent unnecessary equipment downtime.

The high-breaking-capacity construction of the Mersen J087500 supports reliable interruption of fault currents within its specified operating limits. It is therefore well suited to industrial control equipment, power supplies and other applications requiring a compact 2 A time-delay fuse.

Typical Applications

• Industrial control panels.
• Power supplies and transformer circuits.
• Automation and process control equipment.
• Instrumentation and measurement systems.
• Electronic equipment with start-up inrush currents.
• OEM machinery and electrical assemblies.
