The trip characteristic and ampacity differ; a circuit review is required before substitution."},{"question":"Will S202M-K40UC drop into a panel that was specified around SH202T-C20 without rewiring?","answer":"The physical footprint and DIN-rail mounting are identical, but the trip curve and current rating differ.
