CM-PFE: technical identity and handover
Identify CM-PFE by its complete marking before ordering. CM-PFE is a three-phase sequence monitoring relay within an engineered system, so the connection and project context matter as much as the family name.
Verified technical identity
| Technical item | Verified value / selection note |
|---|---|
| Complete designation | CM-PFE |
| Product family | CM-PFE |
| Component role | three-phase sequence monitoring relay |
| Function | Phase sequence and phase-failure supervision |
| Variant | CM-PFE versus CM-PFE.2 supply and range must be checked |
| Output | Confirm contact arrangement on the installed unit |
| Final configuration | Confirm exact nameplate, hardware revision and order options before purchase |
The CM-PFE entries above are the starting points for selection. Check the exact nameplate and current manufacturer documents for options or revisions not expressed by the short type code.
Acceptance evidence
The site test for CM-PFE should include: Apply the site-approved phase-failure and sequence test and record alarm/reset behavior. Save the observed values, status indications and responsible reviewer's approval.
For equipment containing CM-PFE, document any parameter restore, wiring change, safety check or protective-setting check before release to normal operation.
System interface
CM-PFE serves this duty: Supervise the feeder phase condition used by the panel's permissive or alarm circuit. Draw the path from supply or network through CM-PFE to the connected load or signal.
Record the real terminal positions, connected cable, controller or protection logic, and the environmental conditions around CM-PFE. These define the acceptance boundary for a replacement.
Order-code questions
Before buying CM-PFE, resolve this critical match: Match monitored voltage, phase sequence, contact state, delay and supply arrangement. Request an explicit statement of any hardware, firmware or accessory difference.
If another code is offered for CM-PFE, compare it against the installed drawings and the manufacturer's variant data. Do not infer interchangeability from enclosure appearance or shared prefix.
