The Siemens 5SL6340-7 is described by Siemens as: Miniature circuit breaker 400 V 6kA, 3-pole, C, 40 A.
The rated current must match the cable cross-section and the tripping characteristic must suit the load; both are printed on the front of the breaker and listed in the Siemens table below.

Compatibility and replacement
Match the number of poles, the rated current and the tripping characteristic (B, C or D) to the old breaker and to the cable it protects.
Replacement checklist
- Look for signs of overvoltage, water or heat damage in the cabinet so the new part does not fail for the same reason.
- Check the mounting (DIN rail or screw fixing) and the terminal type (screw or spring-loaded) of the old unit.
- Check the supply voltage and wiring of the old unit before installing the new one.
