Shunts
DIN 43703 Shunts
860 Series
Designed and manufactured to
comply with the requirements of
DIN43 703 this range of shunts
provides an accurate D.C. millivolt
signal, exactly proportional to the
system current, to drive ammeter
indicators, overload protection and
control devices.
Features
Ratings 1A up to 15000A
Shock and vibration tested
Low temperature
coefficient
Long term stability Specification
The 860 series complies with DIN43 703 for dimensions and DIN43 780 for performance.
When specified they conform to IEC51 (BS89).

temperature: working range is -20°C to
+60°C
Maximum load: for maximum accuracy the
load should not exceed 0.1%
of the shunt current rating
Construction
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
DIN 43703: For maximum long term stability
and strength, copper manganese resistance
elements are both rivetted and soldered into
slots in the end blocks.
Installation
For maximum heat dissipation, mount shunts
in the horizontal plane, with the blade facing
vertical. 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 silicone grease
applied to the contact surface area. Shunts
are supplied with bolts, nuts and washers.
These must be tightened fully. Ample
ventilation should be provided.
Potential Leads
The length/resistance of leads should be
allowed for up to 25A, end blocks are
mounted on an insulated base which provides
support and protection against damage to the
resistance elements. An element cover is
fitted on ratings up to 10A.
Warning
Shunts are uninsulated and protection
against accidental contact may be necessary
in order to comply with Health & Safety
regulations.
