The Siemens 5SY6020-7KV26 is a 1+N-pole miniature circuit breaker (MCB) rated 230 V with a 6 kA breaking capacity and a C-curve 20 A trip characteristic. The neutral pole is on the left side of the assembly, and the overall depth is 70 mm.
The N-left orientation fixes the neutral busbar position relative to the phase on the DIN rail; verify your distribution board's neutral bar alignment before committing the assembly.
