Current transformer Rittal SV 9677.180 — white, single-piece industrial measurement transformer

Rittal SV 9677.180 is a single-piece current transformer with a white finish, designed for industrial measurement and monitoring applications. Delivered as one unit, this compact transformer converts a primary current into a proportional secondary current for metering, protection relays, and control systems. Its enclosure and form factor make it suitable for integration into switchgear and measurement assemblies where a space-efficient measurement transformer is required.

Advantages

The single-piece design simplifies installation and reduces the number of connection points compared with multi-part transformers. A white housing offers a neutral appearance for switchgear cabinets and measured assemblies while providing clear marking and wiring visibility. The transformer provides stable current transformation for reliable metering and protective device operation and is built to meet typical industrial durability requirements.

Suitable for

• Integration into switchgear and control panels requiring compact current measurement
• Feeding energy meters and power-quality monitors with proportional secondary current
• Supplying protection relays and control systems that require isolated current inputs
• Industrial environments where space-efficient, single-piece transformers are preferred

When it may not be suitable

This single-piece transformer is intended for typical industrial measurement and protection tasks; it may not be suitable where specialized accuracy classes, non-standard primary conductor sizes, or custom mounting hardware are required. For applications demanding precise metering at an uncertified accuracy class or where separate split-core access is necessary for retrofit without power interruption, a different transformer type should be considered.

Key specifications

• Form factor: single-piece (solid core) current transformer
• Color/finish: white housing
• Application: industrial measurement, metering, protection and control
• Output: proportional secondary current suitable for meters and relays
• Mounting: designed for integration into switchgear and measurement assemblies

How to use

Install the transformer into the switchgear or panel following applicable electrical standards and safety procedures. Route the primary conductor through the transformer's aperture or connect as specified by the panel design. Connect the secondary output to the metering device or protection relay using secure, appropriately rated wiring and ensure correct polarity and grounding per the system documentation. Verify connections and perform functional testing at low loads before placing the system into normal operation.

What to consider before purchase

• Confirm primary current range and compatibility with the system's conductor or busbar dimensions
• Verify required accuracy class and whether this transformer's specifications meet metering or protection requirements
• Ensure secondary current rating and burden compatibility with connected meters and relays
• Check mechanical fit and mounting options inside the intended switchgear or control cabinet

Usage recommendations

Use this transformer with appropriate secondary shorting and protective procedures during installation and maintenance. Match the transformer's secondary rating to the measuring instruments and protection devices to maintain measurement integrity and system safety.
