Fuses (UL recognized)UL Recognized fuses for branch circuit protection per NEC are listed below. Check thatthe operating time of the fuse is below 0.1 seconds. The operating time depends on thefuse type, supply network impedance and the cross-sectional area, material and length ofthe supply cable. The fuses must be of the “non-time delay” type. Obey local regulations.FuseInput current(A)Drive typeACQ580-34- Type DIN43653SizeManufacturerVAUN = 400 V, IEC170M54082Bussmann690400212246A-4170M54102Bussmann690500257293A-4170M64103Bussmann690630321363A-4170M64113Bussmann690700401442A-4170M64123Bussmann690800401505A-4170M64143Bussmann6901000505585A-4170M64143Bussmann6901000569650A-4UN = 480 V, IEC170M54082Bussmann690400209246A-4170M54102Bussmann690500233293A-4170M64103Bussmann690630307365A-4170M64113Bussmann690700363442A-4170M64123Bussmann690800363505A-4170M64143Bussmann6901000389585A-4170M64143Bussmann6901000441650A-4UN = 480 V, UL (NEC)170M54082Bussmann690400209240A-4170M54102Bussmann690500258302A-4170M64103Bussmann690630307361A-4170M64113Bussmann690700363414A-4170M64123Bussmann690800418477A-43AXD00000586715Note:• See also Implementing thermal overload and short-circuit protection (page 55).• In multicable installations, install only one fuse per phase (not one fuse per conductor).• Fuses with higher current rating than the recommended ones must not be used. Fuseswith lower current rating can be used.• Fuses from other manufacturers can be used if they agree with the ratings and themelting curve of the fuse does not exceed the melting curve of the fuse mentioned inthe table.Technical data 113
