Product Details:

Types Available : Tape Wound & Cast Resin Confirming to IS:2705
CORE: Toroidal core of high Permeability silicon steel.

RANGE & APPLICATION:

METERING CT: Accuracy will be selected on the basis of the instrument i.e. when installed at a far away from CT the secondary is chosen as 1A instead of 5A.

PROTECTION CT: Meant for Circuit Breakers & Relays

WOUND PRIMARY:
When the ratio is low it becomes difficult to obtain good result with single & primary turn. For this both primary & secondary turns are wound on the toroidal core.

ELECTRICAL FEATURES:
Rated Frequency - 5-60hz * Class of Insulation - E * Rated time thermal current ith - 60 in * Nominal surge current ldyn - 2.5 ith (minimum 100 kA at all window type Ct’s) * Highest voltage for equipment Um - 0.72Kv (other voltages on request) * Rated power-frequency withstand voltage - 4Kv / 1min (Other voltages on request) Instrument security factor - Fs5 or Fs10

SPECIAL NOTES:
Ct’s available in class 0.5 and 0.2 and other accuracy class available on request * Ct’s also available with 1A sec current * Other VA’s are as per customer requirement.

MECHANICAL FEATURES:
* Unbreakable, flame retardant, self-extinguishing / Nylon casing of grade UL 94 V2
* Cores are made from high grade CRGO material
* Dual coated copper wire having class of insulation H.
* Nickel plated secondary terminals with plus minus screws of 0.5Nm.
* Integrated secondary terminal caps.

Product Details:

Ae Make DC SHUNTS are available for current ratings from 5A to 15000A with mV drops of 50-150 mV. DC Shunts are manufactured with Stringent Quality Control confirming to IS: 1248. Shunts consist of manganin rods/wire soldered or silver brazed to Brass/ Copper Blocks. The shunts are artificially aged after manufacturing, then tested on full load.

APPLICATION
Shunts are used for measuring current in DC Applications by connecting them to Moving Coil Panel meters, Digital Meters or other measuring devices. Shunts can also be used in Control Devices such as Power Supplies and Battery chargers or for over Load Protection.

TECHNICAL SPECIFICATIONS
Accuracy Class- 1 or 0.5 
Over load-- Shunts are capable of with standing temperatures upto 120º C without any permanent alteration in physical or electrical properties. Over loads and faults which results in temperature of this magnitude can be safely handled.   
Temperature Co-efficient- 0.002% per degree centigrade, above ambient temperature in still air, with free ventilation, temperature not exceeding 120º C  at the centre and 90ºC at the ends.
Insulation- Shunts are supplied un-insulated and protection against contact should be installed where applicable.
Over loads (Brass Ended) - Continuous- 1.2 x Rated Current, 5 seconds- 4 x Rated Current upto 30 seconds,
5 seconds- 10 x Rated Current upto 5 seconds
Ambient Temperatures- Calibration -20ºC
 Working Range -20 ºC + 60 ºC

TYPES:-
Compact Brass Ended- These shunts are often requested for special applications due to small size. Manufactured to IEC: 51 Class-1, they can be current rated from 5-50A with 25, 50, 60, 75, and 100mV output.
Standard Brass Ended- These Shunts are heavy duty type and provide accurate DC mili Volt signal suitable for measuring instruments and circuits and are manufactured as per IS: 1248, Class-1 or Class 0.5 with current rating from 5A- 15000A and 50- 300mV output.
Installation- For maximum heat dissipation, mount shunts in the horizontal manner, with the blade, standing vertical. Utilize the full end block surface area. Ample ventilation should be provided. Bus Bar should be adequately rated, clean and level, with a thin coat of silicon grease applied to the contact surface area. Use flat and tension washers under the nuts and tighten fully.
