At 6 A it protects a 1.5 mm² copper circuit at 400 V three-phase, which is typical for lighting subcircuits or control transformers in a building-services panel. That figure matches the 4.5 kA rating under both EN 60898 (household standard) and IEC 60947-2 (industrial standard), so it qualifies for either installation code — a useful dual-certification for panels that cross between residential and light-industrial use. The 3-pole (3P) configuration switches all three phases simultaneously, with no neutral pole switching. It occupies 3 width units (54 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm — standard 5SL3 footprint that drops into any SENTRON distribution board or generic DIN enclosure without surprises.
