That's a mild slope — you don't lose much headroom even in a hot enclosure, but if you're packing breakers tight in a panel above 50 °C, factor in that 1–2 A drop per circuit. ## Built-in accessories and panel fit Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep, so it fits a standard 3-pole MCCB slot in a SENTRON or generic distribution panel without surprises.","metaTitle":"Siemens 3VA1032-4ED32-0HC0 SENTRON MCCB, 32 A, 3-Pole, 70 mm","metaDescription":"Siemens 3VA1032-4ED32-0HC0 SENTRON molded case circuit breaker, 32 A rated, 3-pole, line protection.
