Megger MOM600A – Micro-Ohmmeter

• Test current up to 600 A for demanding high-current resistance measurements
• Micro-ohm measurement capability for detailed contact and joint analysis
• Microprocessor-controlled testing for stable current and repeatable readings
• Designed for circuit breakers, busbar joints, disconnectors, and high-current connections
• Clear digital display and straightforward controls for efficient operation
• Robust, portable design suited to substation and industrial testing

The Megger MOM600A Micro-Ohmmeter is built for demanding contact resistance testing in high-current equipment. It delivers test currents up to 600 A, which helps simulate real operating conditions during measurements. As a result, technicians can evaluate circuit breaker contacts, disconnectors, and busbar joints with greater confidence. The instrument measures resistance in the micro-ohm range, making it easier to identify developing contact problems. A microprocessor-controlled current source maintains stable output during each test. This improves measurement consistency and reliability. Meanwhile, the clear digital display presents results quickly and clearly. Simple controls also help technicians set up tests with minimal effort. With its rugged construction and portable form, the MOM600A fits well into demanding substation maintenance and commissioning work.
