276C
Current Canceling TransformerThe Model 276C Current-Canceling Transformer monitors two of the three phases, and cancels the effect of the current signal in the third phase, which would otherwise cause a phase shift error. The Model 276C accepts input directly or from two standard current transformers (CTs), corrects for the third leg, and provides a single current output to the controller.The Model 276C is UL Recognized and CSA Certified. For use with Models 421 or 422 in 3-phase applications.

279B-120
DC Current Monitor1 – 10A DCThe Model 279 DC Current Monitor is a single set-point DC current monitor. It can sense either 1-10 Amps DC (24VAC or 120VAC) or 0.1-1 Amps DC (120VAC). The units have an input frequency of 50/60 Hz. The standard version, the 279B, has a screwdriver adjustable trip and hysteresis setting on top of the device. The hysteresis setting adjusts from 0% to 100%, and can be set fully clockwise for manual reset operation. A remote adjust version, the 279C, has a remote trip adjustment and a remote reset button. An LED indicator is provided on both versions to indicate when the relay is energized (current above the trip setting. )The 279B plugs into a standard 8-pin octal socket; the 279C plugs into a standard 11-pin socket.
