Detachable Design
It can be easily disassembled to adapt to a variety of installation environments, particularly those constrained by limited space.
CT103 With 250A Current Capacity
For typical applications where currents of up to 250 amperes are needed.

Self-Powered: No Batteries, No Limits
The CT10x is designed to derive power directly from the measured circuit, eliminating the constraints of batteries while ensuring seamless operation.

Superior Accuracy
Outperform other competitors on the market, CT10x boasts an impressive high sampling frequency of up to 3.3kHz, guaranteeing unparalleled accuracy and detail.

Efficient Energy Tracking At One-Second Interval
Calculate accumulated ampere hour in real-time at a one-second interval. This enables precise current consumption monitoring and analysis, achieving goals such as energy conservation and reduced operational costs.

External Wire Temperature Sensor
An external wire temperature sensor is available, triggering alerts when the wire temperature reaches a set threshold.

Irregular Current Status Alert
