Siemens SENTRON 5SY4332-7XX01 — 3-pole C-curve MCB, 32 A
Rated breaking capacity stands at 10 kA per EN 60898 and 20 kA per IEC 60947-2, with a UL 1077 / CSA C22.2 No.235 interrupting rating of 5 kA at 400 V AC. Rated operational voltage is 400 V AC (3-phase) with a maximum of 440 V AC in multi-phase operation; DC rating is 72 V maximum.
Width is 54 mm (3 width units at 18 mm each), height 90 mm. Combined terminals at both top and bottom simplify busbar and cable connections. Sealable design allows lockout/tagout for maintenance isolation.
Ambient temperature range spans -40 °C to +75 °C, with humidity derating: max 95% RH at 55 °C, tapering to 35% at 75 °C. Energy limiting class 3 per EN 60898, meaning it limits let-through energy effectively for downstream protection coordination. The part carries the standard approvals implied by its EN, IEC, UL, and CSA ratings — suitable for panels destined for European, North American, and other markets that accept these certifications.
