High Voltage Fuses from ABB - Connecting World Power Systems
T&D UK distribute ABB indoor high voltage fuses - the ABB fuse ranges include : high voltage capacitor fuses, high voltage current limiting fuses, HRC fuses, motor fuses, transformer fuses and expulsion fuses.
ABB CIL high voltage fuses are a full range, current limiting type capacitor fuse designed for indoor applications. The primary application for ABB CIL fuses is individual capacitor unit fusing for metal-enclosed high voltage equipment.
Low power losses ensure ABB current limiting fuses are suitable for compact high voltage switchgear and for fuse switch disconnectors combination. ABB CEF current limiting fuses are back-up type. They have a zone between the minimum melting current and the minimum breaking current where the fuse links may fail to interrupt and this zone is very narrow. ABB current limiting fuses offer low minimum breaking current, low power losses, low arc-voltage and a high breaking capacity.
High voltage fuse-links for rail traction applications are characterised by high rupturing capacity, short circuit current limiting and low switching voltages.
ABB high rupturing capacity fuses are short-circuit current limiting with low rated minimum breaking current (Imin), low switching over voltages (Um) and dimensions to DIN and IEC standards.
IEC 644 applies to high voltage fuses used with motors started direct-on-line on alternating current systems. High voltage fuses used in motor circuits must have the ability to withstand, without deterioration, the repeated surges associated with motor starting. Special connection elements can be delivered in cases where fuses have to be paralleled.
ABB transformer fuse-links are used to protect high voltage equipment against short-circuits in indoor voltage transformers. Protection of switchgear equipment is ensured by the unlimited breaking capacity and short circuit current limitation. Compact dimension ABB WBP type high voltage fuse-links can be used in various types of switchgear, including flame-proof types.
