The Siemens SENTRON 3VA2040-7KP32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current Iu of 40 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its ETU850 electronic trip unit delivers interrupting ratings of 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V — the 330 kA figure at 240 V is the headline for high-fault utility or transformer-fed panels. The 86 mm depth, 105 mm width, and 181 mm height fit standard MCCB panel cutouts; the IP40 front-face protection suits enclosed distribution boards where dust ingress is a concern.
