Megger Mjölner 600 600 A Micro-ohmmeter

Megger Mjölner 600 600 A Micro-ohmmeter — High-Current DualGround Testing

The Megger Mjölner 600 is a 600 A micro-ohmmeter for accurate contact and joint resistance measurement with the safety of patented DualGround™ testing — keeping both sides of the test object grounded throughout. Delivering up to 600 A DC and microhm resolution, it is ideal for testing large circuit breaker contacts, busbar joints and high-current connections in substations and heavy industry where higher test currents are required.

Key Features

• DualGround™ safety — both sides of the test object stay grounded throughout the measurement for safer working.
• 600 A test current — adjustable up to 600 A DC in 1 A steps, with up to 300 A continuous load capacity.
• Microhm resolution — measures 0 to 999.9 mΩ with resolution down to 0.01 µΩ.
• High accuracy — typically ±6 µΩ at low resistance for confident results.
• Wide application — large circuit breaker contacts, busbar joints, high-current connections, switches, cables and welding points.
• Multi-language LCD — English, German, French, Spanish and Swedish.
• Universal input — 100–120 / 200–240 V AC, 50/60 Hz; −20 °C to +50 °C operation.
• Standards — meets IEEE C37.09 and IEC 62271-1.

Applications

The Mjölner 600 is ideal for substation and heavy-industry test teams measuring the resistance of large circuit breaker contacts, busbar joints, disconnectors and high-current connections — with DualGround safety and the higher test currents needed for large apparatus.
