The 5SL6625-6 occupies 4 modular-width units (72 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm — standard for a 4-pole SENTRON 5SL6. IP20 with connected conductors; the touch-protection feature means the terminals are shrouded when wired, meeting the finger-probe requirement for distribution boards. The neutral conductor is switched internally, so no separate neutral link is needed downstream. ## Thermal derating and environmental range At 40 °C it derates to 23.79 A; at 45 °C to 23 A; at 55 °C to 21.85 A. If the panel runs warm — say a crowded enclosure near a boiler or drive — factor that curve into the load calculation.","metaTitle":"Siemens 5SL6625-6 SENTRON MCB, 4P B-Curve 25 A 6 kA","metaDescription":"Siemens 5SL6625-6 SENTRON miniature circuit breaker, 4-pole B-curve, 25 A rated, 6 kA breaking capacity per IEC 60898.
