Height is 90 mm. The 18 mm width means it fits a standard single-module slot in any SENTRON or third-party distribution board; no adapter required. Terminal accepts solid conductors up to 35 mm², sufficient for the rated current of this pole. Power loss per pole is 1.6 W in hot operating state at rated AC current — relevant for thermal derating when multiple breakers are ganged in an enclosure.
No last-time-buy or phase-out constraints apply.
This part is sourced to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing.
The 5SY4116-7CV is a 1-pole MCB with the same 15 kA IEC 60947-2 breaking capacity and 72 V DC rating, but it is rated 230 V AC single-phase versus 440 V AC for the 5SN6116-8CP. The 5SN part carries a higher AC voltage rating, so substitution requires verifying the system voltage does not exceed 230 V phase-to-neutral.
The depth is 76 mm, with an installation depth of 70 mm.
The width is 18 mm, corresponding to 1 modular width unit.
Yes, both parts share the same 18 mm width, 76 mm depth, and 70 mm installation depth, so the mechanical fit is identical. However, verify the system voltage: the 5SN6116-8CP is rated 440 V AC multi-phase, while the 5SY4116-7CV is rated 230 V AC single-phase. If the panel voltage exceeds 230 V phase-to-neutral, the 5SN part is the correct fit.
