A comprehensive range of reliable and accurate current transformers (CTs) for low-voltage industrial, commercial and residential metering applications. CT range is an essential component of the AC measurement system, designed to work optimally with panel instruments, transducers and energy meters. These CTs are made following stringent plant quality assurance procedures, which fully comply with applicable standards (IEC: 61869-2 & IS: 16227-2). The range includes CTs for primary current from 30 A to 4000 A and secondary current of 5A / 1 A.


  • Control panels, drives and switchboards
  • Motor control centres
  • Power control centres
  • For mounting on busbars and transforming various primary
  • current into 5 A or 1 A secondary standard


  • Dual terminal for fixing CT shorting link
  • Finger safe terminal cover for preventing accidental shock
  • Easy to mount
  • Protection class IP-20
  • Flame Retardant Polycarbonate (as per UL 94 V0)


  • Wide range of system current ratings, bus bar sizes, case widths and apertures
  • Various mounting options like wall mounting, cable mounting, bus bar mounting, etc.
  • Wire sealable terminal covers
  • Hinged terminal covers
  • Terminal with M4 screw, with dual connection facility, giving access from both sides of transformers
  • Second pair of terminal can be used for shorting of CT before disconnection
