Breaking capacity and selectivity — what the ratings mean for your panel
The 5SY7350-6: The 15 kA rating under EN 60898 is the standard for residential and light commercial final circuits; the 20 kA under IEC 60947-2 covers industrial distribution where fault currents run higher. The DC 15 kA rating (IEC 60947-2) matters for battery-backed or rectifier-fed loads. For UL 1077 / CSA C22.2 No. 235 installations, the listed 5 kA applies — confirm your available fault current stays within that limit before specifying.
Mounting and integration — DIN rail, any position, quick assembly
The 5SY7350-6 snaps onto a DIN rail via the quick assembly system and can be mounted in any position. It occupies 3 modular width units (54 mm total width) with a depth of 76 mm and an installation depth of 70 mm. The IP20 rating (with connected conductors) means it belongs inside an enclosure — not exposed to washdown or outdoor conditions. Combined terminals top and bottom simplify busbar and outgoing wiring.
Environmental and compliance — halogen-free, silicon-free, wide temperature range
Halogen-free and silicon-free construction suits applications sensitive to outgassing — clean rooms, medical equipment, or sealed enclosures where corrosion matters. The operating temperature range spans -40 °C to 75 °C, with derating for humidity (95% RH up to 55 °C, tapering to 35% at 75 °C). Pollution degree 3 and overvoltage category III confirm it for industrial environments where conductive contamination and transient overvoltages are expected.
