Has anyone gone stone crazy enough to measure the reaction times (to a short) of the PSX1-AC versus the breaker already on the PH180 transformer? Or a fuse? Or a modern circuit breaker? The money IS an issue. I have 8 blocks. This thing PSX1-AC is selling for $60 shipped per unit. So I would be at $480 to protect my layout. OTOH, $480 could be the repair bill on one loco, right? Sigh....I ordered one to test it.
