Megger / Multi-Amp MS-1A Overload Relay and Circuit Breaker Test Set
The MS-1A test unit has a patented circuit consisting of a continuously variable autotransformer which supplies a Multi-Amp output transformer, thus providing stepless control of the output current. Integral metering, timing and control circuitry are included. The unit is housed in a convenient suitcase-type enclosure for easy portability.
The MS-1A will test time-current characteristics of motor overload relays and molded case circuit breakers rated up to 100 amperes by simulating overloads up to 300% of their rating. Auxiliary applications include testing of in-line motor cut-outs, fuse links, meters and rationing current transformer.
