Murata ACM3P-4-AC1-B-C , LED Digital Panel Multi-Function Meter for Current, 22.1mm x 36.22mm

ACM3P - Three-Phase AC Ammeters

ACM3P series 3-phase AC ammeters measure and display the true-RMS values of 2- or 3-phase ac mains current. A front panel touch switch enables the selection of a continuous reading of any of the three phases. All ACM3P ammeters are functionally complete, with built-in L1, L2 and L3 current transformers, no other user-supplied components or hardware are required.
Their miniature size is ideal for UPS backup power sources, power strips, alternative energy metering, and any other applications that require precise monitoring of 2- or 3-phase ac current.
