Megger MOM600A 600 A Micro-ohmmeter

Megger MOM600A 600 A Micro-ohmmeter — High-Current Contact Resistance Testing

The Megger MOM600A is a 600 A micro-ohmmeter designed to measure contact resistances in high-voltage circuit breakers, disconnecting switches, knife-contact fuses, busbar and line joints. Delivering up to 600 A DC and microhm resolution with ±1% accuracy, it provides the higher test currents needed for large apparatus in substations and heavy industry.

Key Features

• 600 A test current — up to 600 A DC for accurate low-resistance measurement of large high-current connections.
• Microhm resolution — measures 0–1999 µΩ with 1 µΩ resolution.
• High accuracy — ±1% of reading ±1 digit at 100–600 A test current.
• Wide application — HV circuit breakers, disconnectors, knife-contact fuses, busbar and line joints.
• Managed duty cycle — up to 15 seconds at 600 A (230 V model) with a 5-minute rest.
• Universal mains input — 115/230 V AC, 50/60 Hz.
• Rugged & portable — 356 × 203 × 241 mm, 25 kg, 0 °C to +50 °C.

Applications

The MOM600A is ideal for substation and heavy-industry test teams measuring the contact resistance of large high-voltage circuit breakers, disconnectors, busbar and line joints where 600 A test currents are required.
