Comparison

Resolution:
The obsolete HVMH305200 was offered into the early '90s and was replaced by the HVMB305200 which has an improved Minibreak load interrupter switch and mechanism with higher Fused fault closing rating at 63k vs. 40k.
Both have the same dimensions. 66"h x 25.5"w x 25.25"d but the former was offered in either a NEMA 1 or NEMA 3R box and the current product is offered in a NEMA 1/3R box.
