Where ammeter indicators are ordered with
the shunts, leads 1 metre long, total
resistance 25mΩ should be used.
Highest quality materials, rugged design and
advanced manufacturing techniques are used
throughout. The substantial solid brass end
blocks have conservatively rated contact
surface areas and fixing hole dimensions to
IEC51: (BS89): For maximum long term
stability and strength, copper manganese
resistance elements are both rivetted and
For maximum heat dissipation, mount shunts
in the horizontal plane, with the blade facing
vertical. If the shunt is mounted in the
vertical position the '+ positive' potential
terminal should be the lower or bottom one
due to the "Peltier" effect. Utilise the full end
block surface area. Ample ventilation should
be provided. Busbars should be adequately
rated, clean and level, with a thin coat of
Shunts with metric threads and dimensions
are fully compliant with and approved to
DEF 66–13 and have a silver soldered end
block and painted resistance elements.
Shunts are uninsulated and protection
against accidental contact may be necessary
in order to comply with Health & Safety
regulations.
Insulated mounting blocks available for 882 and 883 sizes
Other lengths are available to order.
soldered into slots in the end blocks. Above
2000A, end blocks are multibladed. For
current ratings below 30A model 881 base
mounted shunts are supplied as standard
unless otherwise specified. For base
mounted shunts up to 100A see our model
829 range.
silicone grease applied to the contact surface
area. Use M10 (3/8in) fixing bolts with model
882 and M12 (1/2in) for all other shunts.
Use flat and tension washers under the nuts
and tighten fully.
Insulated mounting blocks are available for
models 882, 883.
They are supplied with removable solder tags
on the potential terminals as additionally
required by MoD (Naval). Consult factory for
more details.
