It generates the gate-firing pulses that control the SCRs during motor start and stop — if this board fails, the soft starter loses its ability to phase-control the motor current. The product designation is printed circuit board, confirming it is a populated board assembly, not a bare board or a kit. It is a direct-fit replacement for the original board in those frame sizes. ## Compliance documentation on record The substance prohibitance date is listed as 03/01/2017, which aligns with the RoHS compliance cutoff for the EU directive. This gives quality and documentation teams a reference point for verifying the board's restricted-substance status against their own compliance requirements.","metaTitle":"Siemens 3RW4766-0VC50 Firing PCB, 690 V, for 3RW44 Size 5/6","metaDescription":"Siemens 3RW4766-0VC50 firing PCB rated 690 V for 3RW44 soft starters Size 5 and 6.
