Why Choose the Mersen Y093654 DC Cylindrical Fuse-Link?
The Mersen Y093654, also designated DC10GC11C5, is a compact cylindrical fuse-link designed to protect direct-current electrical circuits against damaging overcurrents and short-circuit faults. Its current-limiting operation helps reduce the peak fault current and energy transferred to conductors, power supplies and connected equipment.
Manufactured by Mersen, formerly known as Ferraz Shawmut, the Y093654 forms part of the HelioFuse range of high-voltage DC protection products. Its durable cylindrical construction provides dependable interruption performance in applications where conventional low-voltage AC fuse-links may not be suitable.
With a rated current of 5 A, a maximum operating voltage of up to 1,050 V DC and a compact 10 × 85 mm format, the Mersen Y093654 is suitable for compatible fuse holders in photovoltaic, auxiliary power and industrial DC systems. It also carries the catalogue designation 1500 CP GLC 10.85 5.

Reliable Protection for High-Voltage DC Circuits
Direct-current faults can be difficult to interrupt because a DC circuit does not naturally pass through a zero-current point. A correctly selected DC-rated fuse-link is therefore essential for safely extinguishing the electrical arc created when the fuse element operates.
The Mersen Y093654 is designed to interrupt excessive DC current rapidly and limit the resulting fault energy. This helps protect cables, power conversion equipment and connected components while reducing the risk of extensive damage within the wider electrical installation.
Typical Applications
- Photovoltaic power systems.
- High-voltage DC auxiliary circuits.
- Industrial DC power supplies.
- Battery-backed electrical systems.
- Power conversion and inverter equipment.
- Control panels and specialised DC distribution circuits.
