Snubber Resistor
(1)
(1) All parts are ceramic, wirewound, non-inductive winding.
Part Number
(2)
(2) Resistors are series connected for a total of 60 Ω per snubber for 180/360A assemblies and 30 Ω per snubber for 600A assemblies.
A controller has one snubber per pair of SCRs (i.e. 3 snubbers for 2500V, 6 snubbers for 4800V, 9 snubbers for 7200V).
