Mersen Y077853 cylindrical potential transformer fuse-link rated at 7.2 kV AC and 2 A, with a 20 x 190 mm GLF construction for voltage transformers and low-power medium-voltage circuits.
£38.01
The Mersen Y077853, also designated 7200 CP GLF 20.190 2, is a cylindrical medium-voltage potential transformer fuse-link designed to protect voltage transformers and other low-power medium-voltage circuits against damaging short-circuit currents. Its current-limiting operation helps isolate electrical faults rapidly while reducing stress on protected equipment.
Manufactured by Mersen, formerly known as Ferraz Shawmut, the Y077853 combines a durable insulating body with metallic end contacts for dependable service in compatible medium-voltage fuse holders. Its specialised GLF operating characteristic makes it suitable for instrument transformer, metering and auxiliary circuit applications.
With a rated voltage of 7.2 kV AC, a rated current of 2 A and a cylindrical 20 × 190 mm format, the Mersen Y077853 provides compact and reliable protection for low-power medium-voltage equipment. Correct coordination with the protected transformer and fuse holder is essential to ensure safe and effective operation.
Potential transformers and voltage transformers provide reduced-voltage signals for metering, monitoring and protection equipment. A fault within the transformer or connected circuit can produce excessive current that may damage windings, conductors and associated switchgear.
The Mersen Y077853 responds to excessive fault current by melting its internal fuse element and interrupting the circuit. Its current-limiting action restricts both the magnitude and duration of the fault, helping protect low-power medium-voltage equipment and maintain the integrity of the wider electrical installation.
