Rated breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2, which covers most domestic and light commercial fault levels; for higher prospective short-circuit currents (e.g., industrial main panels), a higher-rated MCB or MCCB upstream would be needed. At 40 °C the continuous current derates to 15.23 A; at 45 °C to 14.88 A; at 55 °C to 13.99 A. This derating curve is per the manufacturer's specification and must be applied when the breaker is installed in a warm enclosure or alongside other heat-generating devices. For audit purposes, the thermal derating figures are directly from the datasheet and should be included in any panel thermal calculation. The 5SL3216-6 occupies 2 modular width units (MWU) on a DIN rail, with a width of 36 mm, depth of 76 mm, and height of 90 mm. Installation depth is 70 mm. The breaker is sealable and halogen-free and silicon-free, which is relevant for environments sensitive to outgassing (e.g., clean rooms or certain industrial processes). ## Electrical ratings and compliance The DC rating is 72 V maximum, which limits its use in DC circuits to low-voltage control applications. The energy limitation class is 3, indicating the breaker limits let-through energy to a defined level for coordination with downstream devices.","metaTitle":"Siemens 5SL3216-6 SENTRON MCB, 2-Pole B-Curve 16A 400V","metaDescription":"Siemens 5SL3216-6 SENTRON miniature circuit breaker, 2-pole, B-curve, 16 A at 30 °C, 400 V AC, 4.5 kA (EN 60898).
