It occupies 2 modular width units (36 mm wide) on a DIN rail, with a 70 mm installation depth, fitting standard distribution board cutouts. The 1P+N design switches the line and monitors the neutral, intended for 50 Hz AC single-phase circuits at 230 V nominal. This RCBO carries a 10 kA rated short-circuit capacity per EN 60898 and a 15 kA rating per IEC 60947-2. The higher IEC rating means it can be used in industrial distribution where prospective fault current exceeds 10 kA, provided the installation is coordinated per IEC 60947-2. The 36 mm width (2 MW) and 70 mm depth are standard for SENTRON RCBOs — no overshoot beyond the enclosure base. Ambient range spans -40 °C to 75 °C, with derating applicable above 40 °C for continuous load.","metaTitle":"Siemens SENTRON 5SU1654-1RC40 RCBO 40A C-curve 300mA Type AC","metaDescription":"Siemens SENTRON 5SU1654-1RC40 RCBO, 40 A, C-curve, 300 mA Type AC residual current, 10 kA (EN 60898) / 15 kA (IEC 60947-2).

However, the 5SL6550-7BB is an MCB with no neutral switching or residual current detection; replacing it with an RCBO requires wiring the neutral through the device and may change the circuit's earth-fault protection scheme. A drop-in mechanical swap is possible, but the electrical circuit must be reconfigured."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU1654-1RC40","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SU1654-1RC40 when reusing this data.
