Product details

The Siemens 5SN6416-7CP is a 4-pole miniature circuit breaker (MCB) from the SENTRON 5SN series, built for branch-circuit protection in distribution panels. Rated 400 V AC at 50 Hz, it handles single-phase and multi-phase operation up to 440 V AC, and can also switch DC loads up to 72 V.

Breaking capacity — what the ratings mean

This breaker carries two breaking-capacity ratings because it is certified to separate standards. Under IEC 60947-2 (the industrial switchgear standard) it is rated 15 kA, meaning it can handle higher available fault currents found in industrial power distribution. Which rating applies depends on the installation standard your local code follows; the higher 15 kA figure gives you headroom in mixed-use panels.

Depth is 76 mm, installation depth (the dimension behind the panel door) is 70 mm — standard for a 4-module SENTRON MCB. Accepts solid conductors up to 35 mm², enough for the feeder side of a sub-panel or a large motor circuit. Power loss per pole at rated current in hot state is 1.6 W; four poles total 6.4 W heat to vent inside the enclosure.

Frequently asked questions

What is the difference between the 5SN6416-7CP and the 5SL4363-7?

The 5SL4363-7 is a 3-pole breaker (3 modular width units, 54 mm wide) with a 10 kA rating under both EN 60898 and IEC 60947-2, while the 5SN6416-7CP is a 4-pole breaker (4 units, 72 mm wide) with 6 kA under EN 60898 and 15 kA under IEC 60947-2. The 5SL4363-7 also has a higher per-pole power loss of 5 W vs 1.6 W. They share the same 90 mm height, 76 mm depth, and 70 mm installation depth, so they fit the same DIN-rail enclosure, but you would need to re-terminate the neutral if swapping from a 3-pole to a 4-pole design.

Where can I buy 5SN6416-7CP and how is it quoted?

Available to order against an RFQ through independent distribution channels. Pricing and lead time are confirmed at quote time — no stock-on-hand figures or ship-date promises are published here.

What compliance documentation does Siemens provide for 5SN6416-7CP?

The part is certified to EN 60898 (6 kA) and IEC 60947-2 (15 kA). Standard CE marking applies for the European market. The SENTRON series typically carries UL/CSA listings at the family level; verify the specific UL file number for your jurisdiction against the nameplate.
