5 Product information 5.1 Marking A fuse terminal block shall be marked in a durable and legible manner with the following: a) the name of the manufacturer or a trade mark, by which the manufacturer can be readily identified; b) a type reference permitting its identification in order to obtain relevant information from the manufacturer or his catalogue; c) energy flow direction, if required to ensure protection against electric shock, according to 7.1 .8, e.g. line-load marking or ?. 5.2 Additional information The following information shall be stated by the manufacturer, if applicable, e.g in the manufacturer’s data sheet or catalogue or on the packing unit: a) IEC 60947-7-3, if the manufacturer claims compliance with this standard; b) the rated cross-section; c) the rated connecting capacity, if different from Table 2 of IEC 60947-7-1 , including the number of conductors simultaneously connectable; d) the rated insulation voltage (U i ) of the terminal block base and the fuse-carrier, if applicable; e) the working voltage or working voltage range, primarily determined by the fuse-link or by additional components, e.g. illuminated indicators; f) rated impulse withstand voltage (U imp ); NOTE This value may be marked on the fuse terminal block only if the rated insulation voltage (U i ) or the working voltage is also marked on the fuse terminal block, e.g. 250 V/4 kV. g) rated value of the power dissipation for overload and short-circuit protection (P V ) and rated current of the fuse-link as declared by the manufacturer − in case of separate arrangement, − in case of compound arrangement; h) rated value of the power dissipation for exclusive short-circuit protection (P VK ) and rated current of the fuse-link as declared by the manufacturer − in case of separate arrangement, − in case of compound arrangement; i) operating conditions, if different from Clause 6; j) size of the fuse-link.
