12-Circuit Insights. Single Hub.
Minimal Footprint

CTH01 redefines sub-metering efficiency by monitoring up to 4 three-phase or 12 single-phase circuits simultaneously. This 12-in-1 design drastically reduces hardware investment, simplifies network infrastructure, and fits perfectly into space-constrained electrical cabinets.

Deploy Without Limits: Magnetic, Universal, Pro-Grade

Zero-Downtime Non-Invasive Deployment

Versatile Compatibility from 100A to 4,000A

Professional Analytics with 8kHz Sampling

Beyond standard terminal connections, CTH01 also supports non-invasive magnetic voltage measurement — snap probes onto breaker screws instantly, no terminal wiring or wire stripping required. For current measurement, split-core transformers clamp around conductors without cutting cables or interrupting power. Deploy faster and more securely at scale.

cth01 application scenarios 1 1

Identify waste to slash utility bills. Large facilities often suffer from invisible energy leaks. CTH01 provides granular 12-channel visibility to uncover "dark" energy waste and idle-time consumption. This enables management to implement data-driven actions that optimize energy efficiency and achieve measurable cost savings.

Energy Monitoring and Saving

cth01 application scenarios 2 1

Transparent internal accounting for managed spaces. Property managers in offices, retail chains, and co-working spaces need transparent data for internal cost allocation. CTH01 utilizes real voltage monitoring to eliminate data gaps caused by grid fluctuations, replacing bulky traditional meters with a single, high-precision hub.

Commercial Cost Allocation

cth01 application scenarios 3 1

Harmonic distortion and voltage unbalance are early warnings of equipment stress. CTH01 captures these signatures at 8kHz before bearings fail and lines stop. Predictive, not reactive.

Industrial Predictive Maintenance
