Current transformer Rittal SV 9677.260, light grey, model 9677260

The Rittal SV 9677.260 is a compact current transformer in light grey designed for integration in electrical distribution panels and switchgear. With a slim width of 100 mm and a height of 772 mm, this single-unit transformer is intended for current measurement and protection circuits where space efficiency and reliable performance are required. The unit weighs 11.8 kg and is suitable for installations that need a dedicated transformer for monitoring or control functions.

Advantages

This current transformer provides a narrow profile that helps save panel space while delivering stable current sensing for protection relays and metering devices. Its light grey finish is suitable for standard electrical enclosures and industrial environments. The product’s physical dimensions and single-unit design simplify planning for installation in existing switchgear racks and distribution cabinets.

Suitable for

• Current measurement in distribution panels and switchgear
• Protection circuits for overload and fault detection
• Integration with metering devices and control systems
• Retrofit installations where a compact transformer is needed

When it may not be suitable

This transformer is intended for electrical distribution and switchgear applications; it may not be appropriate for very high-voltage transmission systems or specialty instruments requiring custom transformer ratios or housings. If a complete set of primary cabling accessories or a different mechanical form factor is required, additional components or an alternative product may be necessary.

Key specifications

• Colour: light grey
• Width: 100 mm
• Height: 772 mm
• Weight: 11.8 kg
• Unit quantity: single unit

How to use

Install the current transformer in the distribution panel or switchgear according to the panel layout, ensuring the primary conductor passes through the designated window or terminal area as specified by the switchgear documentation. Secure the unit mechanically and connect secondary outputs to the relevant protection relays or metering devices following standard wiring practices and safety regulations. Verify polarity, test secondary circuits for continuity and insulation, and perform commissioning measurements to confirm correct ratio and operation before placing the circuit into service.

What to consider before purchase

• Confirm the transformer’s dimensions fit the available panel or rack space
• Ensure the device’s rated current range and ratio meet the protection and metering requirements
• Check compatibility with existing protection relays and metering inputs
• Plan for mechanical mounting and required secondary wiring access

Usage recommendations

Install and commission the transformer in accordance with local electrical codes and manufacturer guidelines; perform polarity and ratio checks and use appropriate protective devices on the secondary side when carrying out tests or maintenance.
