The Siemens 3VA1140-4EF32-0AA0-ZD00 is a 3-pole IEC frame 160 molded case circuit breaker with a 40 A rating and a 36 kA interrupting capacity at 415 V (breaking capacity class S). The thermal-magnetic TM240 trip unit provides adjustable overload protection (Ir = 28…40 A) and fixed short-circuit protection (Ii = 5…10 × In). On a DIN-rail or panel-mounted distribution board, the 36 kA SCCR at 415 V gives headroom for high-fault utility feeds; selectivity studies should verify coordination with downstream branch breakers.
