The C-curve (5-10x In magnetic trip) is the standard choice for moderate inrush loads like small motors, transformers, or lighting banks; it won't nuisance-trip on a 32 A motor starting draw but clears fast on a hard short. ## Where it goes Snaps onto standard DIN rail in a panel or sub-distribution board. Four-pole means it switches all three phases plus neutral — typical for three-phase final subcircuits where you need full isolation on the neutral as well. Rated 415 V line-to-line, so it's at home in 400/415 V three-phase systems common across Europe, Middle East, and Asia.","metaTitle":"Siemens 5SL7432-7RC MCB 4P 415V 15kA C-32","metaDescription":"Miniature circuit breaker 415 V 4-pole 15 kA C 32.
