Product details

Siemens SENTRON 5SY6316-6 — 3-pole B-curve MCB

It carries a 6 kA interrupting capacity per EN 60898 and a 15 kA rating per IEC 60947-2, meaning it clears faults up to 15 kA under industrial panel conditions — enough for most distribution subfeeds in mechanical engineering and industry environments. The 3-pole design switches all phases together; no neutral pole here.

This MCB is certified to IEC / EN 60898-1 for household-type installations and IEC / EN 60947-2 for industrial applications, plus UL 1077 for supplementary protection in North America. That dual certification simplifies BOM compliance across regions — the same part number works for a panel destined for Europe or North America. The IP20 rating applies with conductors connected; the enclosure itself is sealable.

Frequently asked questions

Where can I buy 5SY6316-6 and how do I get a price?

The 5SY6316-6 is sourced to order against an RFQ through independent distribution. Submit a request for quote to confirm current availability and pricing.

What compliance documentation does 5SY6316-6 carry?

It is certified to IEC / EN 60898-1, IEC / EN 60947-2, and UL 1077. The part is halogen-free and silicon-free, meeting typical RoHS and REACH requirements for industrial equipment.

What is the interrupting capacity of 5SY6316-6?

6 kA per EN 60898 and 15 kA per IEC 60947-2; at DC under IEC 60947-2 it is also rated 15 kA. Under UL 1077 the rating is 5 kA.
