861-92MG-NWEF

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).

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. 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.
