Overview
The General Electric AB40 50-106221FCSV1ACX is a 3-phase AC wattmeter designed for direct measurement of real power in multiphase electrical systems. This analog panel meter operates at 5 amp line current and 120V coil voltage, providing accurate readings across 50/60 Hz applications. As a discontinued model, this unit is now available only as surplus or used stock, making it ideal for replacement, testing, or legacy system upgrades where exact model compatibility is required.

- 50 Hz and 60 Hz power grids globally
- Direct meter wiring (no external CT/PT required for 5A line current)
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The 50-106221FCSV1ACX may be replaced by modern digital power meters or solid-state versions from GE, Siemens, or Schneider Electric if an upgrade to digital display or communication capability is needed. Direct mechanical equivalents from GE’s legacy AB40 series with identical mounting and terminal layout should be confirmed with distributor technical support.
Works With
- Standard 3-wire (3-phase) power distribution wiring
- Analog instrument wiring and copper conductor termination
- Industrial HVAC and UPS systems requiring real-power monitoring
- Retrofit installations in older industrial and utility panels
