What is the difference between the obsolete 32573- 4 pole spreader accessory for Compact NSJ breaker to 32583 catalog number?

The 32573 was the long terminals shields for spreaders 52.5 mm with U < 500V. The 32583 is the long terminals shields for spreaders 52.5 mm with U > 500V. To rationalize the offering (have one part number instead of two), now we use only the U > 500V type.
