Integrator's spec recap — 5SY4616-7
The Siemens 5SY4616-7 is a 4-pole (3P+N) miniature circuit breaker from the SENTRON family, with a C-curve trip characteristic and a 10 kA breaking capacity per EN 60898, 20 kA per IEC 60947-2, and 15 kA at DC per IEC 60947-2. It is rated for 400 V AC (440 V max in multi-phase or single-phase operation) and 60 V DC (72 V max).
The 10 kA rating under EN 60898 covers the residential and light commercial duty most panel builders encounter. For DC circuits, the 15 kA rating at 60 V (72 V max) covers battery banks and DC bus applications. Under UL 1077 and CSA C22.2 No. 235, the breaker carries a 5 kA rating — sufficient for North American supplementary protection applications.
Snap-on DIN rail mount, 4 MW wide (72 mm). The supply cord can enter from any position (top or bottom feed). Ambient temperature range is -40 °C to 75 °C, with derating for humidity (95% at 55 °C, 55% at 70 °C, 35% at 75 °C). The energy limitation class is 3, meaning it limits let-through energy effectively for downstream equipment protection.
