It sits between the standard K and Z curves in its magnetic-trip threshold — typically 8 to 12 times In — so a 16 A unit holds through a short-duration 128 A to 192 A surge. The 25 kA rated short-circuit capacity (Icn) per IEC 60898 is the full interrupting rating at 230 V AC; that is a full order of magnitude above the 4.5 kA or 6 kA common on downstream B- or C-curve MCBs, which is exactly what selective coordination demands. ## Panel fit and mounting constraints Depth of 76.3 mm and height of 128 mm — verify against your enclosure's internal clearance, particularly if a busbar or cover is tight. Saddle terminals accept conductors up to the rated cross-section; sealable cover is provided for metering-lock applications. IP20 with connected conductors — that is typical for a distribution board interior, not for wet or dust-laden environments. Listed as current-production (active lifecycle stage) from Siemens. No official successor has been published, and the part remains in the SENTRON catalog for new installations and replacement.","metaTitle":"Siemens SENTRON 5SP3716 MCB, 1P, 16A, E-Curve, 25kA IEC 6089","metaDescription":"Siemens SENTRON 5SP3716 miniature circuit breaker, 1-pole, 16 A, E-characteristic, 25 kA breaking capacity per IEC 60898.

Its E-characteristic and 25 kA breaking capacity make it suitable for the incoming feeder position where selective coordination with downstream branch MCBs is required."},{"question":"Will the 5SP3716 drop into a panel specified for the 5SL6516-6YA?","answer":"No — the 5SP3716 is a 1-pole, 16 A, E-curve selective breaker with 25 kA breaking capacity, while the 5SL6516-6YA is a 2-pole (1P+N), 16 A, B-curve breaker with 6 kA breaking capacity. The 5SP3716 is physically taller (128 mm vs 90 mm) and deeper (76.3 mm vs 76 mm), and its E-curve is not a direct functional substitute for a B-curve branch breaker. Rewiring and a coordination study would be required."},{"question":"Where can I buy the 5SP3716?","answer":"The 5SP3716 is sourced and quoted to order against an RFQ through independent industrial-automation distribution.
