GRV8-04 M265 : 10A, 1SPDT, 3Phase 4Wire=M265 Voltage Range: 127V-132V-138V-220V-230V-240V-254V-265VAC(P-N)
GRV8-04D M460 : 8A, 2SPDT, 3Phase 3Wire=M460 Voltage Range: 220V-230V-240V-380V-400V-415V-440V-460VAC(P-P)
GRV8-04D M265 : 8A, 2SPDT, 3Phase 4Wire=M265 Voltage Range: 127V-132V-138V-220V-230V-240V-254V-265VAC(P-N)
General
Applications
-Control for connection of moving equipment(site equipment,agricultural
equipent,refrigerated trucks).
-Control for protection of persons and equipment against the consequences
of reverse running.
-Normal/emergency power supply switching.
-Protection against the risk of a driving load(phase failure).
Function Features
-Controls its own supply voltage(True RMS measurement).
-Set 8-level rated operating voltage through knob.
- Measuring frequency range:45Hz-65Hz.
- Relay status is indicated by LED.
- 1-MODULE,DIN rail mounting.
