Megger MS-2A MGR-MS-2A Circuit Breaker and Overcurrent Relay Test Set
The MGR-MS-2A 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, ground-fault trip devices and overcurrent relays.
The MGR-MS-2A is capable of testing the time-delay
characteristics of overcurrent relays, motor overload relays
and molded-case circuit breakers rated up to 125 amperes,
when following the recommended test procedure of testing
the time delay of these devices at three times their rating.
