The SENTRON 5SQ2360-0KA32 is a 3-pole miniature circuit breaker (MCB) with a B tripping characteristic, rated 32 A at 400 V AC, 50 Hz, and a breaking capacity of 3 kA per EN 60898. The B-curve means it trips between 3 and 5 times rated current — suited for resistive or general-purpose loads where inrush is modest, not for motor circuits with high starting currents. The 3 kA breaking capacity is the maximum fault current it can safely interrupt at 400 V per the standard; verify that the prospective short-circuit current at the installation point does not exceed this value.
Panel fit and integration
The 5SQ2360-0KA32 occupies 3 width units (roughly 54 mm) on a DIN rail, with an installation depth of 55 mm. The IP20 finger-safe enclosure is standard for panel mounting — no washdown rating, so keep it inside the cabinet. Pollution degree 3 and overvoltage category 3 mean it's rated for industrial environments where conductive pollution or transient overvoltages are expected. The 3-pole design does not switch the neutral conductor; confirm your distribution scheme accounts for that.
