The Z curve trips between 2.5 and 5 times rated current — designed for semiconductor protection and sensitive electronic loads where standard B or C curves would allow too much through before tripping. The 10 kA breaking capacity at 400/415 V means it can safely interrupt a fault current up to that level without welding the contacts or cascading failure upstream, which matters for coordination in a distribution board. Snap-on DIN rail mount for standard 35 mm rail in a distribution board or sub-panel. The 4-pole format (3 phases + neutral) handles three-phase loads with neutral protection in a single module width. Z-characteristic makes it the right choice for a branch circuit feeding a VFD input, a UPS bypass, or a control transformer — any place where the inrush is low but the fault current needs a fast trip.","metaTitle":"Siemens 5SL4432-0RC Miniature Circuit Breaker, 32A 4-pole Z","metaDescription":"Siemens 5SL4432-0RC miniature circuit breaker, 32A 4-pole Z-characteristic 10kA.
