Eaton MEM S-Type industrial bolted pattern fuselinks conform with BS 88: Part 2: 1988 and have a breaking range and utilisation category rating of gG (full range breaking capacity for general applications). They are ASTA certified for a breaking capacity of 80kA at 415 and 550V ac.

Motor circuit protection fuselinks having a breaking range and utilisation category of gM (full range breaking capacity for the protection of motor circuits) are available as an extension of the industrial range. Their use in certain circumstances permits savings in the size of associated switchgear. This range of fuselinks are ASTA certified for a breaking capacity of 80kA at 415V ac.

These fuselinks are suitable for the back-up protection in motor circuits, having excellent time lag characteristics and high rupturing capacity.

The following tables should assist in selection of suitable fuse links. The figures are based on the assumption that the starting condition is 8 x f.l.c. for 6 seconds d.o.l. and 4 x f.l.c. for 12 seconds star-delta. Motor kW figures are based on 415V 3-phase.
