The Sigenergy Sigen Sensor TP-CT300 provides precise power monitoring for three-phase 3P3W and 3P4W electrical systems. Designed to integrate smoothly with compatible Sigenergy equipment, the sensor offers a fast 50 ms data refresh rate and 1% power measurement accuracy for responsive system control.

Communication is provided via RS485 using the Modbus RTU protocol at 9,600 bps. The TP-CT300 is supplied with three current transformers, each rated for a maximum operating current of 300 A, with 1 m CT cables and a 24 mm inner diameter. 

Built for straightforward installation, the sensor mounts on a standard 35 mm DIN rail and carries an IP20 ingress protection rating. It is suitable for operation from -25°C to 55°C and supports both 50 Hz and 60 Hz systems. 

The datasheet also states that sensors from two different manufacturers may be supplied interchangeably because they are functionally identical, so the physical appearance and some manufacturer-dependent dimensions may vary between supplied units.
