Product details

The Siemens 5SY6410-6 is a SENTRON miniature circuit breaker — 4-pole, B-curve, rated 6 kA under EN 60898-1 and 15 kA under IEC 60947-2 (and UL 1077 at 5 kA).

At 400 V AC (single- or multi-phase) and 60 V DC (72 V DC max), it handles the common voltage rails in European and Asian machinery. The 75 °C max ambient (derated per the humidity table) keeps it in spec for panels near ovens, drives, or solar combiner boxes.

Panel fit and compliance notes

Rated to IEC/EN 60898-1 (domestic MCB standard) and IEC/EN 60947-2 / UL 1077 (industrial supplementary protector). That dual rating means it passes inspection for both a machine control panel (60947-2) and a building sub-feed (60898-1) without argument from the certifier.

Frequently asked questions

What compliance documentation does Siemens provide for 5SY6410-6?

The part carries IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 certifications. It is halogen-free and silicon-free. Standard Siemens documentation includes the declaration of conformity (CE/UKCA) and RoHS/REACH declarations available on request.
