Sigenergy Sigen Power Sensor TP-CT120-DH (1426000007) – 3-phase energy meter with CT

The Sigenergy Sigen Sensor TP-CT120-DH is a 3-phase energy meter with external current transformers (CT) for the Sigenergy SigenStor ecosystem. This sensor provides real-time power measurement across all three phases via CT clamps with a maximum measuring current of 120A.

Unlike the standard TP-DH sensor, the TP-CT120-DH allows the current transformers to be clamped around existing cables, without interrupting the wiring.

Advantages

• 3-phase measurement via external CT clamps (max. 120A)
• No power interruption required during installation
• 1% accuracy in power measurement
• LCD display for real-time readout
• Seamless integration with Sigenergy equipment
• RS485 / Modbus RTU communication

Applications

• 3-phase SigenStor EC or Sigen Hybrid TP2 installations
• Situations where direct wiring is not possible
• Retrofit projects on existing installations
