The SENTRON 5SQ2560-0KA32 is a 2-pole miniature circuit breaker (1P+N) with a B tripping characteristic, rated 32 A at 240 V AC, 50 Hz. The 32 A rating covers a typical ring-main or a large lighting radial. That 3 kA SCCR matches the typical prospective fault current at the downstream end of a distribution board; upstream coordination with a higher-rated device is assumed for installations with higher available fault current.
DIN-rail integration and panel fit
The 5SQ2560-0KA32 occupies 2 width units (roughly 36 mm) on a standard 35 mm DIN rail, with an installation depth of 55 mm. IP20 finger-safe terminals are standard for enclosed distribution boards. The 1P+N configuration switches both phase and neutral, with the neutral pole switching but not protecting — the overcurrent trip acts only on the phase pole. This is the common arrangement for single-phase final circuits where the neutral is switched for isolation but does not carry a protective device.
