The 7.5 kA rating per EN 60898 at 415 V AC defines the maximum prospective fault current this MCB can safely interrupt under standard conditions. In a panel with mixed loads, the C-curve avoids nuisance trips from brief starting currents that a B-curve would catch. At 1.3 W power loss per pole in hot operating state at rated current, the thermal contribution to the enclosure is modest — two poles dissipate 2.6 W total. In a densely packed DIN-rail enclosure with multiple MCBs, this keeps the internal temperature rise manageable without forced ventilation. ## DIN-rail fit and modular accessories Supplementary devices such as shunt trips, undervoltage releases, or auxiliary contacts can be installed on the 5SL6204-7RC (Product Extension Installable Supplementary Devices = Yes). This allows remote tripping or status feedback without replacing the base MCB. The SENTRON 5SL series is a current-generation platform from Siemens. No successor order code has been announced, and the part carries the full complement of IEC/EN approvals typical for European-distribution-board components.","metaTitle":"Siemens 5SL6204-7RC SENTRON MCB, 4A 2-pole C, 7.5 kA","metaDescription":"Siemens 5SL6204-7RC SENTRON miniature circuit breaker, 4A, 2-pole, C-curve, 7.5 kA per EN 60898 at 415 V AC.

Both share the same 76 mm depth and 70 mm installation depth, so the 5SL6204-7RC will fit the same DIN-rail mounting but occupies 1 fewer modular unit.
