Frequently asked questions

What does the '3+N-pole' designation mean for the Siemens 5SY6606-7 circuit breaker?

The '3+N-pole' designation on the Siemens 5SY6606-7 means it has three poles for the phase conductors (L1, L2, L3) and one pole for the neutral conductor (N). This provides simultaneous switching and protection for all conductors in a three-phase system with a neutral connection.
