## Summary description

Rittal SV 9677.810 is a fixed current transformer with a nominal current output of 150 A. Designed for conductors with diameter 2.5–4 mm and supplied in black colour. It converts primary current to a manageable secondary signal for measurement and protection circuits in electrical panels and switchgear.

## Long description

Rittal SV 9677.810 is a fixed current transformer designed to convert high primary currents into a manageable secondary signal for measurement and protection circuits in electrical panels and switchgear. The unit provides a nominal secondary current of 150 A and is intended for use with single conductors having diameters between 2.5 and 4 mm. Finished in black, this compact transformer is suitable for inductive measurement of current flow in industrial and commercial electrical installations.
Advantages
The transformer offers a stable and linear conversion of primary current to a secondary output, enabling reliable measurement and protection functions. Its fixed design and defined conductor aperture simplify installation in tight panel spaces. The specified conductor diameter range ensures consistent magnetic coupling and measurement accuracy when installed according to recommended practice.
Suitable for
 Current measurement in distribution and control panels
 Protection circuits and motor control systems
 Retrofitting or adding metering points in switchgear
 Inductive sensing applications with single conductors 2.5–4 mm in diameter
When it may not be suitable
This fixed transformer is not appropriate where conductors exceed the specified 2.5–4 mm diameter range or where a split-core design is required for live conductor retrofitting without disconnection. It is also not intended for use as a primary protective device by itself; correct system-level protective relays and fusing should be used.
Key specifications
 Function: Fixed current transformer for inductive measurement
 Nominal secondary current: 150 A
 Conductor diameter range: 2.5–4 mm
 Colour: Black
 Mounting/readiness: Designed for installation in electrical panels and switchgear
How to use
Install the transformer so the single conductor passes centrally through the aperture that matches the 2.5–4 mm diameter range. Ensure the secondary output is correctly connected to the measuring instrument or protection device according to its wiring diagram and the installer follows local electrical codes. Verify polarity and tight electrical connections, and perform calibration or zero checks as required by the measuring equipment manufacturer.
What to consider before purchase
 Confirm the conductor diameter is within the 2.5–4 mm range
 Ensure the secondary nominal current (150 A) matches the downstream measurement or protection device requirements
 Determine whether a fixed-core or split-core transformer is needed for your installation method
 Check panel space and mounting accessibility for installation
Usage recommendations
Install and commission the transformer according to applicable safety standards and the instructions of the measuring/protection device. Use proper protective equipment during installation and verify system grounding and fuse coordination for safe operation.
