The Megger MOM200A is designed to check and measure contact resistances in highvoltage circuit breakers, disconnecting switches (isolators) and busbar joints. This unit is an excellent choice when 200 amperes or less are needed for measurement.

The MOM200A is ideal for finding poor connections since it can put out 100A for extended periods. Its range extending up to 20 milliohms makes it ideal for measuring many different types of connections.


Measures contact resistance in circuit breakers, disconnecting switches, busbar connections, safety devices, etc.
Easy to operate.
Designed for rugged field use.
Highly flexible cable connections.
Portable and lightweight, weighs only 14 kg (31 lbs).
