RMO500C – Accurate Contact Resistance Testing up to 500 A

The initial point of any circuit breaker assessment begins with accurate contact resistance testing.

The RMO500C, the leading model of the RMO-C Series, provides testing with 200 A DC continuous current and can sustain 300 A for up to 10 minutes. For applications that require higher precision, the test current reaches up to 500 A DC for 30 seconds.

Its high-precision module provides increased accuracy, while the Both Sides Grounded (BSG) mode ensures additional safety during testing.

Compact, durable, and easy to operate – the RMO500C helps you complete testing more efficiently. To find out how the RMO500C can enhance your operations, you may preview the brochure at our website.
