Why Choose the Mersen H219726 Medium Time-Lag Miniature Fuse?
The Mersen H219726 is a compact 5 × 20 mm medium time-lag miniature fuse designed to protect sensitive electrical distribution circuits and industrial equipment against sustained overloads and short circuits. Part of the established Mersen 5SM IEC miniature fuse series, it combines dependable fault protection with controlled tolerance of brief current surges.
Its medium time-lag operating characteristic allows short-duration start-up currents to pass without unnecessary fuse operation. This makes the H219726 suitable for circuits containing power supplies, transformers, capacitors and other components that may draw a temporary inrush current when energised.
With a rated current of 0.063 A, equivalent to 63 mA, and a rated voltage of 250 V AC, the Mersen H219726 provides precise protection for low-current control, instrumentation and electronic circuits. Its standard cartridge dimensions allow straightforward installation in compatible 5 × 20 mm fuse clips and holders.
Key Advantages
- Medium time-lag operation tolerates brief normal start-up currents.
- 0.063 A current rating for sensitive low-current circuits.

Balanced Protection for Sensitive Low-Current Circuits
Medium time-lag fuses provide a balance between immediate fault protection and tolerance of short-duration current peaks. They allow normal energisation surges to pass while disconnecting the circuit when an excessive current condition continues beyond the permitted time.
The Mersen 5SM range is designed for electrical distribution circuits and industrial applications requiring compact IEC-format protection. The H219726 is particularly suitable where precise 63 mA protection is required without the nuisance operation that can occur when using a quick-acting fuse.
Typical Applications
- Industrial control and auxiliary circuits.
- Instrumentation and measurement equipment.
- Electronic control systems.
- Low-current power supply circuits.
- Automation and process control equipment.
- OEM machinery and electrical assemblies.
