What this MCB does in the panel
The Siemens SENTRON 5SL6532-7BB is a 2-pole miniature circuit breaker (1P+N) rated 32 A at 230 V AC with a C tripping curve — meaning it holds through moderate inrush (motor starts, capacitor banks) and trips on sustained overloads between 5× and 10× rated current. The neutral pole switches as well, so you get full isolation on both conductors when the breaker opens.
The screw terminals accept solid or stranded copper from 0.75 mm² up to 25 mm², tightened to 2.5–3 N·m. That 25 mm² top end means you can feed a 32 A circuit with a single 6 mm² or even 10 mm² conductor without pigtailing down.
