Current transformer Rittal SV 9677.080, white, single-piece supply

The Rittal SV 9677.080 current transformer is a compact, single-piece device designed for accurate current sensing in switchgear and control panels. Supplied in a white finish, this model is intended for integration into electrical measurement and monitoring systems where a compact transformer is needed. It supports safe isolation between primary conductors and measurement circuits, enabling reliable data for protection relays, meters, or monitoring equipment.

Advantages

This single-piece current transformer offers a compact footprint and straightforward mechanical installation in confined panel spaces. Its construction provides electrical isolation for measurement circuits while maintaining accurate current transformation across the rated range. The white finish assists visual integration into light-coloured enclosures and facilitates identification during installation and maintenance.

Suitable for

• Current measurement and monitoring in switchgear and distribution panels
• Integration with energy meters, protection relays and monitoring systems
• Applications requiring a compact, single-piece transformer for space-constrained installations

When it may not be suitable

This transformer is intended for measurement and monitoring rather than direct power conversion, so it may not be suitable where high-power transformation or primary switching is required. For installations that demand specific secondary ratios, very high accuracy classes, or specialized insulation levels, a different transformer matching those precise technical requirements should be chosen.

Key specifications

• Form factor: single-piece current transformer
• Colour/finish: white
• Application: electrical measurement, monitoring and meter/protection interface
• Mounting: designed for panel or switchgear integration in compact spaces

How to use

Install the transformer around the primary conductor according to the panel layout and wiring diagrams. Ensure the device is mounted securely and oriented as specified by the system documentation, and connect the secondary outputs to the meter or protection relay using appropriate wiring and torque values. Verify polarity and continuity before energising the circuit. After installation, perform functional checks and calibration or configuration of the connected measurement devices as required.

What to consider before purchase

• Confirm the required primary and secondary current range and the necessary accuracy class for your measurement or protection equipment
• Ensure mechanical fit and clearance within the switchgear or control panel, including conductor routing
• Verify compatibility with the meters, relays or monitoring systems to be connected

Usage recommendations

Use the transformer only within its specified current range and mounting orientation. Observe safety procedures for working on live panels and ensure secondary circuits are never left open under load. Regularly inspect connections and verify measurement accuracy during routine maintenance.
