Product details

It provides a breaking capacity of 7.5 kA according to EN 60898 at 415 V AC, making it suitable for residential and infrastructure branch-circuit protection where short-circuit levels stay within that limit.

Physical Fit and Integration

Sealable design allows padlocking the toggle in the OFF position for lockout/tagout compliance during maintenance.

Halogen-free and silicon-free construction supports use in environments sensitive to corrosive off-gassing, such as data centers or clean manufacturing areas.

Power Loss and Thermal Considerations

For a 3-pole breaker at full load, total heat rejection inside the enclosure is 11.4 W — a factor when calculating cabinet thermal rise in a dense DIN-rail layout.

Frequently asked questions

What compliance documentation is available for the 5SL6350-6RC?

The 5SL6350-6RC is halogen-free and silicon-free. It carries an IP20 protection class with connected conductors, overvoltage category III, and pollution degree 2 ratings. Standard Siemens declarations (RoHS, REACH) apply per the SENTRON product family.
