Why Choose the Mersen Z081787 Medium-Voltage Fuse-Link?
The Mersen Z081787, also designated FR36GD32C63P and 36GD32V63P, is a cylindrical medium-voltage fuse-link designed to protect public lighting networks, transformers and specialised electrical distribution equipment against damaging overcurrents and short-circuit faults. Its current-limiting operation helps reduce the thermal and mechanical stresses placed on protected equipment during severe electrical faults.
Manufactured by Mersen, formerly known as Ferraz Shawmut, the Z081787 features a durable insulating body with metallic end contacts for reliable performance in demanding infrastructure and industrial environments. Its gLD operating characteristic is specifically suited to appropriately coordinated medium-voltage lighting and distribution circuits.
With a rated voltage of 3.2 kV AC, a rated current of 63 A and a cylindrical 36 × 190 mm format, the Mersen Z081787 is designed for installation in compatible medium-voltage fuse holders. An integrated striker can operate suitable indication, interlocking or switchgear tripping mechanisms when the fuse-link operates.

Reliable Protection for Medium-Voltage Distribution Equipment
Medium-voltage fuse-links interrupt excessive current before it can cause extensive thermal or mechanical damage to cables, transformers, switchgear and connected equipment. When a short circuit occurs, the internal fuse element operates rapidly and the resulting electrical arc is controlled and extinguished within the fuse body.
The Mersen Z081787 limits both the peak magnitude and duration of fault current, helping protect the wider electrical installation. Its striker can also activate a compatible switchgear mechanism, supporting clear fault indication and coordinated isolation of the affected circuit.
Typical Applications
- Public and street lighting distribution networks.
- Medium-voltage transformer protection.
- Industrial electrical distribution systems.
- Medium-voltage switchgear and fusegear.
- Utility and infrastructure installations.
- Specialised power distribution equipment.
