FC 102 VFD Bypass Panel, 7.5 HP, 3-Phase 460 VAC, NEMA 3R, 3-Contactor Bypass, Main Circuit Breaker
One enclosure holds the drive, EMB2 electromechanical bypass, main breaker, and drive fuses.
Needs 3-phase input power.
A drive input contactor isolates the drive from the line, and a Test position runs the motor in bypass while the drive stays powered.
In bypass the motor runs across the line at full speed, protected by a Class 20 overload relay set to the motor full-load amps.
EMB2 adds automatic transfer to bypass on a drive fault, run permissive, and basic fire mode in bypass.
Key Features
- Bypass: 3-contactor, EMB2 electromechanical
- Drive output current: 13 A at 380-440 VAC, 11 A at 441-480 VAC (continuous)
- Fuses: drive fuses
- RFI filter: standard
