Product details

The Siemens 5SY6415-8 is a 4-pole miniature circuit breaker from the SENTRON 5SY6 family, designed for branch-circuit protection in industrial control panels and distribution boards. Rated 1.6 A at 400 V AC, it protects the downstream wiring and equipment against overloads and short circuits. Breaking capacity is rated at 6 kA per EN 60898 and 30 kA per IEC 60947-2 — the higher figure applies when the breaker is installed with a sufficient upstream fault-current limitation, as specified in the standard's coordination rules.

Mounting and wiring notes

Mounts via the quick-assembly system (DIN-rail clip) in any orientation, occupying 4 width units (72 mm). Terminal capacity accepts solid or stranded conductors from 0.75 to 35 mm², with combined top and bottom terminals for through-wiring.

Frequently asked questions

What is the breaking capacity of the 5SY6415-8?

Rated at 6 kA per EN 60898 and 30 kA per IEC 60947-2 at 400 V AC. The DC breaking capacity is 15 kA per IEC 60947-2 at 72 V DC.

How does the 5SY6415-8 differ from the 5SY7140-8CC?

The 5SY7140-8CC is a higher-current variant (40 A) in the same SENTRON family. Both share the same 4-pole D-curve design and DIN-rail footprint, but the 5SY6415-8 is rated for 1.6 A — intended for control-circuit or small-load protection, not main feeder duty. Panel rewiring is not required to swap between them if the ampacity matches the protected load.

Where can I buy the 5SY6415-8?

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