Product details

Siemens 5SN6316-7CP — 3-Pole MCB, C-Curve, 6 kA / 15 kA

It is rated for 400 V AC supply voltage at 50 Hz, and its breaking capacity is specified at 6 kA according to EN 60898 and 15 kA according to IEC 60947-2 — the higher figure applies when the breaker is installed per the industrial standard's requirements, giving the specifying engineer headroom for higher prospective fault currents in commercial or light industrial distribution boards. It accepts solid conductors up to 35 mm², which covers most downstream feeder and branch-circuit wiring in a sub-distribution board.

Ratings in Context

Rated for multi-phase operation up to 440 V AC maximum, and for single-phase operation also at 440 V AC. The DC rating is 72 V maximum, which limits its use in DC circuits to low-voltage control or battery applications. Power loss is 1.6 W per pole under rated current at AC in hot operating state — relevant for thermal coordination within a multi-breaker enclosure.

Frequently asked questions

Where can I buy 5SN6316-7CP?

This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is the difference between 5SN6316-7CP and 5SL4363-7?

Both are 3-pole C-curve MCBs with the same dimensions (76 mm depth, 54 mm width, 90 mm height) and the same 72 V DC rating. The key difference is breaking capacity: the 5SN6316-7CP is rated 6 kA per EN 60898 and 15 kA per IEC 60947-2, while the 5SL4363-7 is rated 10 kA per both standards. The 5SL also has a higher power loss per pole (5 W vs 1.6 W). For a panel originally specified around the 5SL4363-7, the 5SN6316-7CP will physically fit the same DIN-rail footprint and terminal wiring, but the lower breaking capacity must be verified against the fault-current study before substitution.
