Accuracy class:
Ratings:
The manganin resistance element is silver
soldered into conservatively rated brass end
blocks. These are mounted on to an
insulating, moulded base, drilled to provide
fixing holes.
The current terminals are substantial M8
studs fitted with locknuts and washers.
Connection of the potential leads is made by
M5 slotted hexagon screws.

Shunts can be mounted horizontally or
vertically. For maximum heat dissipation,
mount horizontally with the element in free air
and ensure that the equipment housing
permits adequate ventilation.
Shunts are uninsulated and protection
against accidental contact may be necessary
in order to comply with Health & Safety
regulations.
Model 829 provides an alternative to
the 880 series at ratings below 100A.
Its black moulded base gives the
additional mechanical strength
required for many applications as well
as providing a means of mounting.
It is equally suitable for laboratory
work or for use as a component in
electronic equipment.
1.2 x rated current
continuously 10 x rated current
for 5 seconds at 75mV
Calibrated for 20°C, they can
be used in an ambient range
of -20°C to +60°C.
When mounted as
recommended in freely
circulating air, the temperature
rise should not exceed 90°C at
75mV.
