The Siemens 5SJ6332-7 is a SENTRON 5SJ6 miniature circuit breaker — 3-pole, C-curve, rated 32 A at 400 V AC.
Ratings & fit
The 6 kA breaking capacity is the same under both EN 60898 (domestic/commercial) and IEC 60947-2 (industrial) standards — so it's rated for the industrial panel just as it is for the sub-distribution board. That puts it in the standard range for fixed-installation switchgear in dry, non-conductive environments. DC rating: 60 V maximum. If you're running a DC bus, this breaker is limited to 60 V — above that you need a DC-rated device. The 3-pole unit occupies 3 width units (17.5 mm per pole) on the DIN rail, mounting in any position. That covers unheated warehouses and roof-mounted enclosures in most climates. Mechanical endurance is 20 000 switching cycles typical — fine for panel isolation duty; not a daily-switching contactor replacement.
