Product information

Description

ZAMEL MRP-400A is an expansion module created to accept signals from external current transformers (CT). Designed for DIN-rail mounting in electrical panels, this interface module increases the number of CT inputs available to metering, protection and automation systems. It ensures stable transmission of analogue current signals from transformers to monitoring devices and controllers, enabling centralised energy measurement and reliable integration into existing installations.

Advantages

The module offers additional CT input capacity while maintaining compact dimensions suitable for distribution boards. Its design focuses on stable signal transmission and electrical compatibility with standard CT outputs, reducing the need for rewiring or replacing existing measurement equipment. Mounting on DIN rail simplifies installation and maintenance in industrial and commercial switchgear environments.

Suitable for

  • Expanding CT input count in energy metering systems
  • Integrating additional current measurements into automation and building management systems
  • Connecting extra transformers for protection relays and monitoring devices
  • Retrofit projects in electrical panels where space is limited

Key specifications

  • Function: interface module for current transformer inputs
  • Mounting: DIN-rail compatible enclosure for electrical panels
  • Signal type: analogue current inputs from external CTs
  • Application: energy monitoring, protection and automation integration
  • Form factor: compact module suitable for distribution switchboards

How to use

Install the module on a standard DIN rail inside the distribution panel and connect secondary leads from external current transformers to the designated CT input terminals. Ensure correct polarity and secure terminal connections according to wiring diagrams supplied by the system integrator or manufacturer instructions. Route signal wiring separately from high-voltage or high-noise power cables to minimise interference. After wiring, verify continuity and measurement readings with the supervisory metering or protection equipment before commissioning.

Usage recommendations

Use the ZAMEL expansion module with CTs rated for the expected primary currents and ensure secondary burden and wiring meet the input requirements of the receiving meters or relays; follow local installation standards and perform functional tests after installation.
