That's a shallow curve — only 2 A lost over a 30 °C rise — so it's well suited for a warm panel near a kiln or furnace line where ambient climbs but you can't oversize the breaker. The breaker measures 70 mm deep, 50.8 mm wide, and 130 mm high. That 50.8 mm (2-inch) width per pole is standard for SENTRON 3VA MCCBs — it occupies roughly two 18 mm module spaces on a DIN rail. Maximum power loss is 7.06 W, so no special ventilation is needed in a typical steel enclosure.","metaTitle":"Siemens 3VA1132-4ED26-0AA0 SENTRON MCCB, 2-Pole, 32 A, 121 k","metaDescription":"Siemens 3VA1132-4ED26-0AA0 SENTRON molded case circuit breaker, 2-pole, 32 A rated at 40 °C, 121 kA breaking at 240 V AC.
