The instantaneous design means no intentional delay on short-circuit — it clears fast, which matters for cable protection and selectivity coordination downstream. The 4-pole design protects all three phases plus neutral with a single device, saving DIN rail space compared to separate MCB + RCCB combinations. The 6 A rating is only valid at 30 °C. The datasheet provides a full derating curve: 5.7 A at 40 °C, 5.5 A at 45 °C, 5.3 A at 50 °C, 5.1 A at 55 °C, 5.0 A at 60 °C, and 4.7 A at 70 °C. If your panel runs warm — say 50 °C inside the enclosure — you effectively have a 5.3 A device. The maximum ambient is 70 °C; the minimum is -40 °C. Mounting position is any, which helps in tight enclosures.","metaTitle":"Siemens 5SU1346-6FP06 SENTRON RCBO, B-Curve 6A 4P 6kA 400V","metaDescription":"Siemens 5SU1346-6FP06 SENTRON RCBO, 4-pole B-curve 6A, 6kA breaking capacity per EN 60898, 400V 50Hz.
