Shunts
This base mounted shunt provides an
alternative to the panel meter series at
ratings below 500A. 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 for use
as a component in electronic equipment.

Accuracy: 0.25%
Outputs: 50mV (or) 100mV
Refer to Factory for other outputs
Temperature
Coefficient: 0.002% per °C overall
Construction
The manganin resistance element is hard
soldered into conservatively rated brass end
blocks. These are mounted on to an
insulating, moulded base, drilled to provide
fixing holes.
Installation
Shunts can be mounted horizontally or
vertically. For maximum heat dissipitation,
mount horizontally with the element in free air
and ensure that the equipment housing
permits adequate ventilation.
Warning
Shunts are not fully insulated and protection
against accidential contact may be necessary
in order to comply with Health and Safety
regulations.
