Siemens SENTRON 5SU1336-6FP32 is a 3-pole RCBO (residual current circuit breaker with overcurrent protection) rated 32 A at 30 °C with a B tripping characteristic. It breaks 6 kA fault current per EN 60898 and IEC 60947-2. The 6 kA rating tells you it safely clears a bolted fault up to that level at 400 V AC, 50 Hz, without the arc re-striking or the case rupturing.
Depth is 72 mm; installation depth 70 mm. Mounting position any — horizontal, vertical, inverted — no derating needed for orientation. Supply can enter from top or bottom; no forced busbar order.
Thermal derating and environment
At 40 °C it derates to 30.8 A; at 50 °C to 29.5 A; at 60 °C to 28.2 A; at 70 °C to 26.9 A. Operating range is -40 to 70 °C, with up to 95% humidity.
