Circutor M78014 TP6 Split Core Current Transformer 200/5A, 30x30mm

The Circutor TP6 200/5 (code M78014) is a single-phase split-core current transformer with a 200/5 A transformation ratio and a 30 × 30 mm flat strip aperture. Its split-core construction allows it to be clamped onto existing cables or busbars without disconnecting the supply, making it well suited to retrofit metering work on live circuits where taking the installation offline is not an option.

Features and benefits:

• Split-core design clamps around conductors without interrupting the supply, removing the need to shut down the circuit during installation.
• Accommodates flat busbars and cables up to 30 × 30 mm, covering a broad range of low-voltage distribution board configurations.
• V0 self-extinguishing plastic housing limits flame propagation inside switchgear panels and enclosures.
• Sealable terminals and cable fastening accessories are included, reducing the need for separate hardware orders.
• Dual-frequency rating (50/60 Hz) makes this transformer usable across different regional power networks.

Applications:

• Current measurement and energy monitoring in single-phase low-voltage distribution boards.
• Retrofit metering on energised circuits where disconnecting the installation is not practicable.
• Supplying a 5 A secondary signal to power analysers, energy meters, and protection relays.
• Monitoring busbars or cables in industrial and commercial switchgear with conductors up to 30 × 30 mm in cross-section.
