Under UL 1077 and CSA C22.2 No. 235 the interrupting rating is 5 kA, so check your SCCR study if the panel is specified under North American code. The 1P+N design switches the neutral conductor along with the phase, which is useful in applications where you need to guarantee isolation on both poles — common in single-phase final subcircuits for industrial machinery or mechanical engineering panels. The neutral pole is not overcurrent-protected; it follows the phase pole mechanically. ## Deployment context This MCB is rated for mechanical engineering and industrial environments, with an IP20 protection class once conductors are connected. The ambient temperature range of -40 °C to 75 °C covers most unheated plant floors and heated control rooms, but the derating table shows that above 55 °C you need to reduce the continuous load: at 70 °C the breaker is rated for only 55% of its nominal current, and at 75 °C for 35%. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz. That's enough for most industrial machinery mounted on a panel backplane; if the breaker is on a machine sub-panel subject to continuous high-frequency vibration (e.g., near a large press or shaker), consider additional mechanical restraint or a remote-mounted distribution block. ## Compliance documentation It carries IEC/EN 60898-1 and IEC/EN 60947-2 approvals, plus UL 1077 and CSA C22.2 No. 235. The sealable design allows panel builders to lock the toggle position after commissioning — useful for preventing unauthorized reset on safety-critical circuits.","metaTitle":"Siemens 5SY7516-6 SENTRON MCB, 2-pole 1P+N, B-curve, 15/25 k","metaDescription":"Siemens SENTRON 5SY7516-6 miniature circuit breaker, 2-pole 1P+N, tripping characteristic B, 15 kA per EN 60898 / 25 kA per IEC 60947-2.

The key difference is interrupting rating: the 5SY7516-6 carries 15 kA per EN 60898 and 25 kA per IEC 60947-2, while the 5SY4140-7 is typically rated 10 kA per EN 60898.

For higher fault-current headroom, stick with the 5SY7516-6."},{"question":"Will 5SY7516-6 drop into a panel specified around 5SY4140-7 without rewiring?","answer":"Yes, provided the interrupting rating requirement is met. Both breakers share the same 36 mm width (2 modular units), 76 mm depth, and 90 mm height. The mounting position is any, and the quick-assembly fastening system is identical. The 5SY7516-6's higher breaking capacity (15/25 kA vs. 10 kA) means it can replace the 5SY4140-7 without panelboard modification, but not the reverse — verify the fault current study before substituting downward."},{"question":"What compliance documentation does Siemens provide for 5SY7516-6?","answer":"The breaker is certified to IEC/EN 60898-1 and IEC/EN 60947-2, plus UL 1077 and CSA C22.2 No. 235.
