About the 531X190SRCAGG2
The 531X190SRCAGG2 is a GE Snubber Resistor Card. Snubbers are typically a small network of parts with a function of controlling the effects of circuit reactances. They enhance the performance of switching circuits and typically result in higher efficiency and reliability.
The 531X190SRCAGG2 is a small board with very few components. The board is mounted to a white underlayment that has a small metal stab that allows for easier mounting of the board within the larger system. This metal stab is marked 20920. The board itself is a shaped board with two short ‘legs’ positioned off its bottom edge. The board carries the GE logo, as well as the codes 1991 and 006/00 and 002/00. It is also marked with an alternate board number of F31X190SRCAGG1.
The 531X190SRCAGG2 is populated by two stab-on connectors. These are located in both of the upper board corners. Inside and beside of these components is a MOV or metal oxide varistor. Varistors are variable resistors that provide over-voltage protection by means of voltage-clamping, similar to a zener diode. There are two zener diodes located on the board, directly in front of the MOVs.
The final components located on the surface of the 531X190SRCAGG2 are two wire wound resistors. Each of these is fastened to the board using thru bolts and brackets. Wire wound resistors are designed to withstand frequent start/stop cycles and are ideal for applications involving high currents at a very low resistance value. More information on this part may be found through publications from the manufacturer, such as data sheets or user guides.
