That suits loads with minimal inrush: control transformers, resistive heaters, lighting banks, or long cable runs where a higher magnetic threshold might not clear a bolted fault fast enough to protect the conductor. Rated 400 V AC (440 V max with multi-phase or single-phase operation) at 50/60 Hz. The 3-pole design switches all three phases simultaneously; no neutral pole switching. ## Panel fit — 3 MWU, quick-assembly DIN rail The quick-assembly fastening system clips onto the rail and releases with a screwdriver slot — no loose hardware. Mounts in any position; IP20 with connected conductors. ## Current production — sourced per RFQ Lifecycle stage is current. No successor or phase-out notice on record. Halogen-free and silicon-free construction; sealable with a lockable cover.","metaTitle":"Siemens 5SY4332-5 3-Pole MCB, 10 kA EN 60898-1, Type A","metaDescription":"Siemens 5SY4332-5 SENTRON 3-pole MCB.
