Megger Circuit Breaker Tester DLRO100E, DLRO100X and DLRO100H

The Megger Ducter™ DLRO100 enables low resistance measurement, across multiple applications, in areas without access to mains power. The integral Li-ion battery supplies a constant 100 A current for up to 200 automatic or manual tests enhancing productivity in remote locations.

With a focus on user safety, advanced design features ensure the safe operation of the instrument in the most adverse conditions, including a CAT IV 600 V safety rating in accordance with IEC61010. A DualGround feature is available on the DLRO100X and DLRO100H, which adds to the operators’ safety by grounding both sides ofthe breaker under test.

The tough design, intuitive interface and IP54 (lid open) rating ensure reliability and ease-of-use in the most arduous of conditions.

DLRO100E

The DLRO100E is the entry-level model, tailored for environments that require fundamental testing capabilities with straightforward operation. This model is particularly suited for users who need reliable performance without the need for extensive data analysis or advanced connectivity options. It features a battery-powered system capable of delivering test currents up to 100 A, which is sufficient for most basic low-resistance testing applications.

DLRO100X

The DLRO100X builds upon the foundation laid by the DLRO100E, offering enhanced features such as expanded memory for data storage and the ability to interface with external devices via USB or Bluetooth. This model is designed for technicians who require more detailed data collection and analysis capabilities. The DLRO100X also includes software that facilitates the creation of test reports, making it easier for users to manage and document their testing processes.

DLRO100H

The DLRO100H is the most advanced model in the series, designed for the most demanding applications. It features higher test currents and more sophisticated diagnostic capabilities. This model can generate currents up to 100 A directly and higher currents through the use of additional modules. The DLRO100H is ideal for testing in harsh environments and for applications that require meticulous attention to detail, such as testing large power transformers or for use in substation maintenance.
