The TM210 designation means the thermal pickup is fixed at 1.0 × In and the magnetic short-circuit trip is set at 10 × In — a standard distribution profile that avoids nuisance tripping on transformer inrush or capacitor banks. Breaking capacity hits 187 kA at 240 V AC and still delivers 121 kA at 415 V and 75.6 kA at 440 V, tapering to 17 kA at 500 V and 690 V. Those figures place it comfortably above typical utility fault levels for North American 480Y/277 V and European 400 V panels — the SCCR headroom means it can be installed without cascading an upstream current-limiting fuse for most industrial service entrances. Panel footprint is 130 mm high × 101.6 mm wide × 70 mm deep, with IP40 protection on the front face. The 100 % N-conductor protection design means the neutral pole is fully rated — no derating needed when feeding single-phase loads from a 4-pole breaker in a three-phase-plus-neutral system. ## Thermal derating and operating envelope Rated current holds at 32 A from 40 °C through 50 °C ambient, then gently tapers to 31 A at 55–60 °C and 30 A at 65–70 °C. The breaker accepts an optional motor drive, which is relevant for remote-tripping or generator-paralleling schemes. Ground-fault monitoring is not included; a separate GF module or upstream RCD would be needed for personnel protection. The 101.6 mm width matches the standard 4-inch MCCB pole spacing for North American panelboards — a direct swap into existing SENTRON 3VA1 or competitive 4-pole breaker slots without bus-bar rework. Depth of 70 mm keeps the breaker inside typical 6-inch deep enclosures without door interference.","metaTitle":"Siemens 3VA1132-5GD42-0AA0 SENTRON MCCB, 32A, 4-Pole, 187kA","metaDescription":"Siemens 3VA1132-5GD42-0AA0 SENTRON molded case circuit breaker, 32 A rated, 4-pole, 187 kA at 240 V.
