At 65 °C it still holds 57.35 A, and at 70 °C it holds 48.8 A. The 300 mA trip threshold (type AC, instantaneous) is sized for general-purpose protection of circuits feeding socket outlets or fixed equipment where sinusoidal AC fault currents are the expected waveform. The 4-pole design switches and monitors the neutral conductor for residual current in three-phase TN or TT systems. The part carries the SENTRON brand and is designed to EN 60898 (rated conditional short-circuit current 0.8 kA) and IEC 61008-1 (same 0.8 kA rating). The silicon-free construction is relevant for applications where outgassing must be minimised — e.g., sealed enclosures or sensitive electronic environments. ## Integration notes Depth is 70 mm, width 72 mm, height 90 mm. The 4 MW units occupy four standard DIN-rail positions. Installation depth matches the 70 mm dimension. The 50 Hz operating frequency is fixed.","metaTitle":"Siemens SENTRON 5SV4646-0KL RCCB, 4-pole, 63 A, 300 mA, Type","metaDescription":"Siemens SENTRON 5SV4646-0KL RCCB, 4-pole, 63 A rated, 300 mA residual, Type AC, instantaneous, 10 kA SCCR, DIN rail.
