## Summary description

ZAMEL MRP-200A is an expansion module designed to work with current transformers. It provides additional input capacity for measuring or monitoring current signals from external CTs, enabling integration into protection, metering or monitoring systems. The module is intended for use in electrical panels and control cabinets where increased CT channel count or signal conditioning is required.

## Long description

ZAMEL MRP-200A expansion module is designed to work with external current transformers (CTs) to increase the number of available CT inputs in protection, metering and monitoring systems. The module is built for installation in electrical panels and control cabinets and provides additional input capacity and signal conditioning for current measurement circuits. It supports integration with existing devices that require extra CT channels without altering the primary measuring transformers.
Advantages
The expansion module offers a compact solution to add CT inputs while maintaining signal integrity and electrical isolation. Its design facilitates straightforward mounting in control cabinets and secure connections to secondary circuits of current transformers. The module helps reduce the need to modify existing infrastructure by enabling additional measurement channels, and it is suitable for professional electrical applications where space and reliability are important.
Suitable for
 Increasing CT channel count in protection relay systems
 Adding inputs for energy metering and monitoring panels
 Signal conditioning and distribution of secondary CT outputs
 Retrofit projects where additional current inputs are required
Key specifications
 Function: expansion module for current transformer inputs
 Application: panel and control cabinet mounting for protection, metering and monitoring systems
 Connectivity: secondary-side connections for external CTs (terminal type and count depend on model configuration)
 Electrical isolation: maintains separation between primary and secondary circuits as required for CT installations
 Form factor: DIN-panel compatible housing suitable for electrical distribution boards
How to use
Mount the module in the electrical panel or control cabinet in accordance with local electrical codes and the module’s mechanical dimensions. Connect secondary outputs of external current transformers to the module’s input terminals, ensuring correct polarity and secure terminations. Route conditioned outputs from the module to the protection relays, meters or monitoring devices that require the additional CT channels. Verify that all connections are tight and that short-circuiting links or burden resistors (if applicable) are installed according to the system design and CT specifications before energizing the circuit.
Usage recommendations
Use the module only with compatible current transformers and follow CT secondary wiring practices: never leave CT secondaries open-circuited, observe correct polarity, and keep cable runs and connections tight and clearly labeled. Confirm compatibility with the receiving equipment’s input requirements and consult ZAMEL documentation or a qualified electrical engineer if in doubt.
