AC-PRO-MP® and AC-PRO-MP-II Test Set

The Model B-291-MP secondary injection test set is a single-phase test set specifically designed for testing the operation of the AC-PRO-MP family of microcontroller based trip units manufactured by Utility Relay Co. The B-291-MP test set can test pick-up and time delays of the various protection functions by driving current into theAC-PRO-MP and AC-PRO-MP-II on the secondary side of the CT circuit. This test set supports AC-PRO-MP and AC-PRO-MP-II trip units programmed for 60 or 50 Hertz operation. The test set will test the AC-PRO-MP and AC-PRO-MP-II trip system with the exception of the CTs and associated wiring harness.
