## Summary description

Rittal SV 9677.865 is a through-type current transformer with a nominal current output of 250 A and conductor diameter compatibility 2.5–4 mm. Finished in black, it provides accurate current measurement and isolation for monitoring, protection and metering in switchgear, control cabinets and industrial installations.

## Long description

Rittal SV 9677.865 is a through-type current transformer designed for inductive measurement of current flow. It delivers a nominal output current of 250 A and accepts conductors with diameters from 2.5 to 4 mm. Housed in a black enclosure, this compact transformer is intended for use in switchgear, control cabinets and industrial installations where reliable current sensing, isolation and interface to monitoring or protection equipment are required.
Advantages
The through-type design allows easy installation without disconnecting the primary conductor. Its 250 A nominal output supports integration with standard protection relays and meters, and the specified conductor diameter range ensures compatibility with common feeder and sensor cables. The black housing provides a neutral appearance and mechanical protection for the magnetic core and secondary winding.
Suitable for
Current monitoring and metering in switchgear and distribution panels
Integration with protection relays and measurement instruments
Applications requiring electrical isolation between primary conductor and secondary measurement circuit
Industrial control cabinets and machine panels with conductors Ø 2.5–4 mm
When it may not be suitable
This transformer is intended for inductive measurement and is not a primary power device; it must be used with appropriate secondary circuits and protective equipment. It is not suitable where conductors exceed the specified diameter range or where a different transformation ratio or physical mounting style is required.
Key specifications
Type: Through-type (window) current transformer
Nominal secondary output: 250 A
Primary conductor diameter compatibility: 2.5–4 mm
Colour: Black housing
Function: Inductive current measurement, isolation for protection and metering
How to use
Install the transformer by passing the live conductor through the window, ensuring the conductor fits within the 2.5–4 mm diameter range. Secure the unit in the control cabinet or on the mounting surface per the enclosure design and local installation rules. Connect the secondary output to the measurement or protection device using appropriately rated wiring and ensure correct polarity. Verify that the secondary circuit is never left open under load and that the installation complies with applicable electrical safety standards.
What to consider before purchase
Confirm conductor diameter is within 2.5–4 mm for a secure fit and accurate measurement
Ensure the 250 A nominal output matches the input range of your meter or relay
Check physical mounting and available space in the switchgear or cabinet
Verify compatibility with required safety and installation standards
Usage recommendations
Use the Rittal SV 9677.865 with properly rated secondary wiring and protective devices. Avoid opening the secondary circuit when the primary is energized, and perform commissioning checks with suitable instruments to confirm correct polarity and expected output before putting the system into service.
