Product Description

The JC17S-333mV split core current sensor provides a 333mV output signal when the source signal is 200A.  The JC17S-333mV can be connected directly to a meter for high accuracy energy metering. The JC17S-333mV enables one meter to monitor a range of current ratings by simply changing the main CT. These features help keep meter designs small and efficient while tracking power usage with high accuracy. Also, voltage over-output is limited for safety.


  • Input: 20-240Aac (200 Amp Rating)
  • Output: 333mV (at rating)
  • Size: 17mm  (click here to view the 24mm or 36mm sizes)
  • Connection: Screw terminals

  • Energy sub-metering
  • Power metering
  • Power quality monitoring
  • Equipment monitoring (HVAC & pumps, etc.)
  • Distributed measurement system


  • Compact, light-weight
  • Simple installation
  • Over-voltage protection circuit is installed for added security/safety


  • Accurate within 1% for currents of 10% to 120% of current rating
  • Nylon-spring, output-terminal, secure locking hinge, one-touch structure makes installation inside existing an breaker-box easy
  • Isolated plastic case that conforms to UL94-V0

  • If the core contact surface is hit the internal core material can be damaged and effect accuracy
  • The core material contact surface is waterproof; however, it can rust, after removing the rust with WD-40 or CRC5-56 it is still usable
  • Please use only the original output screws, it is not recommended to replace them
  • Use twisted pair wiring for the leads
