It handles the gate-firing signals that control the thyristor stack in the soft starter's power section. Rated for 600 V, this PCB is the control-side board that translates the starter's logic commands into the firing pulses for the SCR modules. If you are servicing a 3RW4443 soft starter and the firing stage is suspect, this is the direct swap-in board. This PCB carries a Substance Prohibitance date of 03/01/2017, confirming compliance with RoHS-like substance restrictions effective from that date.","metaTitle":"3RW4743-0VC80 Firing PCB 600 V for 3RW44, Size 3, SIRIUS","metaDescription":"Siemens 3RW4743-0VC80 firing PCB rated 600 V for 3RW4443 soft starter Size 3.
