BS 88 industrial fuses - gG and gM curves
BS 88 gG and gM Industrial fuses
• The fuse complies with standard EN 60269-2
section II and standard BS 88 part 2.
• These fuses are designed for :
- “General purpose use” protection (gG type)
- motor protection (gM type)
• This fuse range insures an excellent current limitation for all overloads on a large range of applications.
Their size cannot allow exchange by other fuses
of higher rating in their range.
They are screwed into fuseholders or bolted
directly onto busbars, or in fuse interruptors disconnectors.

gM
This data is based upon normal starting
conditions and usual efficiency and
power factor.
Conditions such as long run-up times,
large numbers of start in succession,
high ambient temperature or abnormal
transients during start/delta switching
may necessitate adjustments to fuse-link
selection.

Curves and derating comply with BS88 standard part 1
and 2 sections 2.1 and 2.2 of 1988.
* Derating also applies, to additional current ratings.
- When the fuse-link is mounted in the open, the elevated
temperature is the ambient air temperature (Ta).
- When the fuse-link is mounted in an enclosure, the elevated temperature is the internal “fluid environment temperature” (Te) within the enclosure.
When it is not known, it should be assumed to be 15°C
higher than the ambient air temperature external to the
enclosure, i.e. Te = Ta + 15°C.
Examples :
- 100 fuse-link mounted in the open at an ambient air temperature of 65°C. Current carrying capability = 100A.
- 200A fuse-link mounted in the open at an ambient air temperature of 60°C. Current carrying capability = 195A.
- 400A fuse-link mounted in an enclosure having an internal temperature of 65°C. Current carrying capability = 370A.
- 800A fuse-link mounted in an enclosure with an unknown internal temperature and an external ambient air temperature of
40°C. Assume the internal temperature is 55°C (40°C + 15°C).
Current carrying temperature = 740A.
• The fuse comply with standard EN 60269-2 section II and standard BS88 part 2.
• This fuses are designed for :
- “general purpose use” protection, (gG type)
- motor protection (gM type)
• This fuse range insures an excellent current limitation for all overloads on a large range of
applications.
Their size cannot allow exchange by other fuses
of higher rating in the F type range.
They are compact and can be connected with
clips.
