Because of they are cheaper, simpler and much more reliable than alternative protecting systems, they used widely.they commonly form part of fuse-switch combination units,or in some cases they are used as stand-alone device to provide the sole protection of equipment.they have equal design for indoor and outdoor applications. EFO High-voltage current limiting fuse-links have high breaking capacity and back-up type. Back-up type fuses can break all currents from min. breaking currents (I3),to max. breaking currents (I1). Their striker system serves as an optical indicator and same time actuate a switching device or circuit breaker with its force. EFO High-voltage current limiting fuse-links are producing according to IEC 08-1 with ISO 9001 quality system. The most significant features of EFO High-voltage current limiting fuse-links - High breaking capacity which proved with type test - Reliable interruption of minimum breaking currents - Equal design for indoor and outdoor applications - Low temperature rise, because of low power dissipation - Low joule integral values - Reliable sealing for humidity and water - Reliable operation of striker mechanism - Low switching voltages at interruption - Melting elements resistant to aging - Production from 3, kv to 3 kv and A to 0A - Upon a request,fuse links can be supplied into no-standard dimensions.

Inside of the thermal striker pin there is temperature sensitive element which reacts in case of temperature increasing of the fuse-link due to various reasons.thermal striker pin is convenient for the protection of the fuse enclosure of SF switchgears which requires additional protection features againgst inadmissible temperatures of certain switchgear parts.
