Megger MOM200A 200 A Micro-ohmmeter

Megger MOM200A 200 A Micro-ohmmeter — Contact Resistance Testing

The Megger MOM200A is a 200 A micro-ohmmeter designed to check and measure contact resistances in high-voltage circuit breakers, disconnecting switches (isolators) and busbar joints. Delivering up to 200 A DC and microhm resolution with ±1% accuracy, it is a rugged, reliable instrument for substation and industrial test teams.

Key Features

• 200 A test current — up to 200 A DC for accurate low-resistance measurement of high-current connections.
• Microhm resolution — measures 0–1999 µΩ (1 µΩ resolution) and 0–19.99 mΩ (10 µΩ).
• High accuracy — ±1% of reading ±1 digit.
• Wide application — HV circuit breaker contacts, disconnectors, isolators and busbar joints.
• Managed duty cycle — 100 A for 5 minutes on / 15 rest; 200 A for 20 seconds on / 5 rest.
• Universal mains input — 115/230 V AC, 50/60 Hz.
• Rugged & portable — 280 × 178 × 246 mm, 14.6 kg, 0 °C to +50 °C.

Applications

The MOM200A is ideal for substation and industrial test teams measuring the contact resistance of high-voltage circuit breakers, disconnectors, isolators and busbar joints during commissioning and maintenance.
