Product Description：

LMCK series is a miniature current transformer, clamp on CT. It has the characteristics of small size, light weight, and easy installation. Rated secondary output can be mA, mV, 1A, or 5A.  Inner hole size is 10mm up to 50mm. The flame-retardant plastic housing, protected from moisture, stable in performance, and require no maintenance. The secondary winding can not be open-circuited in service.

Features:

  • The structure of the self-locking, safe, easy to install, portable
  •  Wide range of sizes to accommodate big cables or bus-bar
  •  Isolated plastic case recognized according to UL94-V0
  •  Wires plugs as customer’s requirement.
  • Laser printing available.
