Megger RCDT330-RCD Tester

The Megger RCDT330 RCD Tester stands at the forefront of electrical testing technology, offering advanced capabilities for assessing the functionality and safety of residual current devices (RCDs). This state-of-the-art tester is designed to meet the comprehensive needs of modern electrical professionals who require precision, efficiency, and versatility in their testing equipment.

Key Features of the Megger RCDT330 RCD Tester:

The Megger RCDT330 is more than just a tester; it is a comprehensive solution that offers unparalleled functionality for the testing of all types of RCDs. Whether for routine safety checks, detailed electrical system analyses, or compliance with regulatory standards, the RCDT330 provides the accuracy, reliability, and ease of use that professionals need to perform their tasks effectively and efficiently.

• Extensive Testing Range: The RCDT330 is capable of performing 1/2I, 1xI, and 5xI tests on a wide range of RCDs, including general, selective (time-delayed), and programmable types. With the ability to handle RCD ratings from 10 mA up to 1000 mA, this tester provides the flexibility needed to address all standard and specialized testing requirements.
• Advanced Data Management: One of the standout features of the RCDT330 is its capacity to store up to 1000 test results in non-volatile memory, ensuring that data is preserved even when the instrument is powered off or when the batteries are depleted. This feature is crucial for large-scale testing projects where data integrity and management are paramount.
• Downloadable Results: The inclusion of USB connectivity and supplied download manager software allows for the seamless transfer of test results to computers. Results are downloaded as CSV (Comma-Separated Values) files, making it easy to integrate data into spreadsheets and reports for analysis, record-keeping, and compliance documentation.
• User-Friendly Interface: The RCDT330 enhances usability with a memory bar graph that acts as a ‘Fuel Gauge’, visually indicating the amount of memory utilized. This intuitive display helps users manage device capacity and plan their testing procedures more effectively.
