Product details

SENTRON 5SP4163-7 — 63 A C-curve MCB, 1-pole, 10 kA

It carries a 10 kA breaking capacity per EN 60898 and a 20 kA rating per IEC 60947-2 at 400 V AC — the higher IEC figure gives headroom for industrial panel coordination where fault currents exceed the residential standard.

The dual breaking-capacity rating matters for panel coordination. Rated 400 V AC, single-pole switching. For a 230/400 V TN system the breaker clears line-to-neutral faults on a single-phase branch; on a three-phase panel each pole protects its own phase independently.

Frequently asked questions

What is the breaking capacity of 5SP4163-7?

10 kA per EN 60898 and 20 kA per IEC 60947-2 at 400 V AC. The higher IEC rating supports industrial panel coordination where fault levels exceed residential limits.

Where can I buy 5SP4163-7?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for your volume and delivery requirements.

What does the C-curve mean on this breaker?

The C tripping characteristic means the magnetic trip activates between 5× and 10× the rated current (315 A to 630 A for this 63 A unit). It is suited for moderate inrush loads such as small motors, lighting banks, and general-purpose branch circuits.
