What this breaker is and what it does
The Siemens 3VA1132-6ED32-0AA0-ZD00 is a 3-pole IEC frame 160 molded case circuit breaker rated for 32 A continuous load with a fixed thermal-magnetic trip (TM210, FTFM). Its headline breaking capacity is 70 kA at 415 V — that's the Icu, the maximum fault current it can safely interrupt without welding or exploding. For a 32 A frame, that's a high-interrupting-capability (class H) device, sized for high-fault locations like a main distribution panel or a transformer secondary where available fault current is stiff.
Key ratings and what they mean for fit
The overload protection (Ir) is fixed at 32 A — no adjustment dial. The short-circuit pickup (Ii) is fixed at 10 x In, so 320 A instantaneous. That means it's a straight thermal-magnetic breaker with a fixed curve; you're not going to dial in a lower pickup for a motor start or a transformer inrush. It's line protection, not motor protection. The fixed Ir and Ii make it a drop-in replacement for a BOM line that already specifies those exact settings.
