The Siemens 3VA1132-6EF42-0AA0-ZD00 is a 4-pole IEC frame 160 circuit breaker with a breaking capacity class H rating of Icu=70kA at 415 V. The TM240 ATAM thermal-magnetic trip unit gives you adjustable overload protection (Ir=22 A to 32 A) and fixed short-circuit protection (Ii=5 to 10 x In). In=32 A is the nominal rating; the Ir dial lets you match the breaker to the actual load current, not the other way around.
Deployment and integration
The 4-pole configuration with N-conductor unprotected is a common arrangement for 3-phase + neutral systems where you want the neutral bus solid (no overcurrent protection on N) — typical in IEC distribution boards.
