Megger MS-2

The MS-2 test set is used around the world by several thousand utility companies, industrial plants and electrical service organizations. Using the latest technology, Model MS-2 is a self-contained test set that incorporates a variable high-current output and appropriate control circuitry and instrumentation for testing thermal, magnetic or solid-state motor overload relays; molded-case circuit breakers; and ground-fault trip devices.

Features and benefits:

• Digital memory ammeter: High-accuracy, direct reading instrument has read-and-hold memory for measurement of short-duration currents.
• Digital, multi range timer: Crystal-controlled, high accuracy instrument with auto ranging measures operating time to 1 millisecond.
• High-current output: Provides instantaneous currents up to 750 amperes through a 125 ampere breaker.
• Rugged and lightweight: Unit weighs only 33 lb (15 kg) and is tough enough to withstand daily field or plant use.
• Solid-state output initiate circuit: Solid-state circuit eliminates need for contact maintenance.

Input: Input Voltage (specify one): 120 V OR 240 V, 50/60 Hz, 1f

Output Ranges: The output is continuously adjustable in four ranges to accommodate a variety of test-circuit impedances: 0 to 5 A at 120 V max. 0 to 25 A at 24 V max. 0 to 120 A at 6 V max. 0 to 240 A at 3 V max.

Output Capacity: The output circuit is designed to permit short duration overloads and the output ranges will provide several times their current rating, provided the output voltage is sufficient to push the desired current through the impedance of the test circuit.
